In a kite, the measures of a pair of opposite angles are $50°$ and $108°$ . Find the measure of one of the other angles in the kite.
The measure of one of the other angles in the kite is equal to 101°
What is a kiteA kite is a quadrilateral which implies the sum of its interior angles is equal to 360°.A kite is symmetrical about its main diagonal and the angles where the adjacent pairs of sides meet are equal. It can be viewed as a pair of congruent triangles with a common base.
Considering one of the congruent triangles which consists of half the angles 50° and 108°, and one of the other angles in the kite.
Let x represent one of the other angles so that we evaluate for its measure as follows:
x + 54° + 25° = 180° {sum of interior angles of a triangle}
x + 79° = 180°
x = 180° - 79° {subtract 79° from both sides}
x = 101°
Therefore, the measure of one of the other angles in the kite is equal to 101°

The price of a watermelon at a fruit stand goes up 7 cents each month. The first month the stand was open, a watermelon cost $1. 25. What will the cost of a watermelon be in the 30th month?.
The price of a watermelon at a fruit stand goes up 7 cents each month. The first month the stand was open, a watermelon cost $1. 25, then the cost of a watermelon in the 30th month will be $4.45
In the 30th month, the cost of watermelon will be $4.45.
To calculate this, you must multiply the initial cost of $1.25 by the number of months since the stand opened (30). That gives us $37.50. Then, add the total amount of cents that have been added each month
7 cents x 30 months = 210 cents
This brings the total up to $4.45.

Given the function f(x) = x + 1 and the linear function g(x), which function has a greater value when x = 2?.
The function f(x) = x + 1 has a greater value when x = 2 than the linear function g(x), as it is an increasing linear function.
The function f(x) = x + 1 has a greater value when x = 2 than the linear function g(x). To prove this, we can calculate the two values:
f(2) = 2 + 1 = 3
g(2) = a * 2 + b (where a and b are constants)
Since a and b are constants, the value of g(2) will remain the same regardless of the value of x. Therefore, since the value of f(2) is greater than the value of g(2), we can conclude that f(x) has a greater value when x = 2 than the linear function g(x).

A rocket is launched in the air. Its height in feet is given by h= -16t^2+112th=−16t 2 +112t where tt represents the time in seconds after launch. How many seconds have gone by when the rocket is at its highest point?
The rocket is at its highest point 3.5 seconds after launch.
What is the function?The function is defined as a mathematical expression that defines a relationship between one variable and another variable.
To determine the time when the rocket is at its highest point, we need to find the value of t when h is a maximum. To do this, we can take the derivative of h with respect to t, and set it equal to 0.
h = -16t²+112t
∂h/∂t = -32t + 112 = 0
Solving for t we get,
t = 112/32 = 7/2 = 3.5 seconds

What is an Angle?An angle is a figure in Euclidean geometry made up of two rays that share a common terminal and are referred to as the angle's sides and vertices, respectively. Angles created by two rays are on the plane where the rays are located. The meeting of two planes also creates angles. We refer to these as dihedral angles.
A figure called an angle is one in which two rays originate from the same point. The two rays that make up the angle are referred to as its arms or sides, and this point is known as the angle's vertex. Reflex angles are those that are higher than 180 degrees but smaller than 360 degrees.

The first side of a triangle measures 5 inches less than the second side. The third side is 3 inches more than the first side. The perimeter of the triangle is 17 inches. What is the length of the second side?
The length of the second side is 10/3 inches or 3.33 inches. The triangle is a scalene triangle.
What is a variable?
A variable is a characteristic that can be measured and has multiple values. Variables include height, age, income, province or country of birth, school grades, and type of housing. Variables are divided into two types: categorical and numerical.
Given that the measure of the first side is 5 inches less than the second side. The third side is 3 inches more than the first side.
Assume that the length of the second side is x.
The length of the first side is x-5 inches
The length of the third side is (x-5) + 3 inches
= x - 5 + 3
= x - 2 inches.
The perimeter of a triangle is the sum of all sides of a triangle.
The perimeter of the triangle is x +( x-5) + x - 2
According to the question,
x +( x-5) + x - 2 = 17
Combine like terms:
(x+x+x) + (-5-2) = 17
3x - 7 =17

the solid bounded by the elliptic cylinder 4x2 + z2 = 4 and the planes y = 0 and y = z + 2
By substituting the limits of integration and solving the definite integral, the volume of the solid is approximately 3.57 cubic units.
What is integration ?
Integration is a fundamental concept in calculus that deals with the problem of finding the total change in a quantity over a given interval. It is the reverse process of differentiation, which deals with finding the rate of change of a quantity.
We can think of slicing the solid into thin horizontal slices, each parallel to the y = 0 plane. The cross-section of each slice with the elliptic cylinder will be an ellipse. The area of each ellipse can be calculated using the formula for the area of an ellipse, which is πab, where a and b are the semi-major and semi-minor axes of the ellipse.
The semi-major axis of the ellipse is 2, and the semi-minor axis is √(4 - 4x^2) = √(4(1 - x^2)) = 2√(1 - x^2). So the area of each slice is A(x) = π(2)(2√(1 - x^2)) = 4π√(1 - x^2)
The height of each slice is dy = dz = dx, since the slices are parallel to the y = 0 plane and the height of each slice is equal to the change in y or z between two consecutive slices.
So, the volume of the solid is ,
∫ (4π√(1-x^2)) dx from x = -1/2 to x = 1/2
By substituting the limits of integration and solving the definite integral, the volume of the solid is approximately 3.57 cubic units.

Given,
Line l₁ passes through point (4,2)
Equation of the line l₁ passing through a point (x', y') ≡ (4, 2), if its slope is m₁:
y-y' = m₁(x-x')
y-2 = m₁(x-4) --------- (a)
Line l₂ passes through the points (x₁, y₁) ≡(-2,2) and (x₂, y₂) ≡ (2,5)
Slope of line l₂ (m₂) = (y₂-y₁)/(x₂-x₁)
⇒m₂ = (5-2)/(2-(-2))
⇒m₂ = 3/4
since l₁ and l₂ are parallel
then slope of l₁ will be equal to l₂
⇒ m₁ = m₂
⇒ m₁ = 3/4
Putting value of m₁ in equation (a)
y-2 = 3/4(x-4)

solve an equation to find x.
-
The required equation is 4x = 2(2x + 2) + 2(2x) and the value of x is -1.
What is the perimeter of the rectangle?The perimeter of a rectangle is defined as the addition of the lengths of the rectangle's four sides.
The perimeter of a square is 4 times the length of one side, and the perimeter of a rectangle is 2 times the length plus 2 times the width.
Since the perimeters of the square and rectangle are equal, we can set the two expressions equal to each other and solve for x:
4x = 2(2x + 2) + 2(2x)
4x = 4x + 4 + 4x
4x = 8x + 4
Subtracting 4x from both sides:
0 = 4x+4
Subtracting 4 from both sides:
-4 = 4x
Dividing both sides by 4:
x = -1
