The vertex angle of an isosceles triangle measures 42°. A base angle in the triangle has a measure given by (2x + 3)°. What is the value of x? What is the measure of each base angle?
Answer:
x = 33base angles: 69°Step-by-step explanation:
The sum of angles in a triangle is 180°. In an isosceles triangle, the base angles are congruent.
For this, it is easiest to find the base angles first. If we let b represent the measure of one of them, the sum of angles is ...
2b +42 = 180
b +21 = 90 . . . . . . divide by 2
b = 69 . . . . . . . subtract 21
The measure of the base angles is 69°.
__
Then we can find the value of x from its relation to the base angle measure:
(2x +3)° = 69°
2x = 66 . . . . . . . . . divide by °, subtract 3
x = 33 . . . . . . . . divide by 2
The value of x is 33.
Answer:
x = 33
each base angle measures 69°

how to solve 28, 53,45 right triangle side lengths
Step-by-step explanation:
I am not sure what you mean.
do you mean to see, if this can be a right-angled triangle, and if so, what is the Hypotenuse, and what are the legs ?
I assume this to be the case.
so, we must be able to build a Pythagoras equality
c² = a² + b²
28² = 784
53² = 2809
45² = 2025
indeed, we see right away, 45² + 28² = 53²
confirmed, it is a right-angled triangle, with 53 being the Hypotenuse.

PLEASE HELP I AM DESPERATE!!!
Answer:
Statements:
m<b = 180 - m<a
m<c = 180 - m<d
m<b = m<c
180 - m<a = 180 - m<d
Reasons:
The measure of m<b is the angle of a straight line subtracted with m<a. The measure of m<c is the angle of a straight line subtracted with m<d. If m<a and m<d are equal, m<b and m<c are equal.
Step-by-step explanation:
We know, m<a = m<d
So, we need to prove m< b = m<c
Let's start by defining what b and c is
m<b + m<a = 180 This is because a straight line is 180 degrees
m<b = 180 - m<a
m<c + m<d = 180
m<c = 180 - m<d
With this, we can substitute in proof
m<b = m< c
180 - m<a = 180 - m<d
180 - m<a = 180 - m<a

Three water pipes are used to fill up a swimming pool. The first pipe alone takes 8 hours to fill the pool, the second pipe alone takes 12 hours to fill the pool, and the third pipe alone takes 24 hours to fill the pool. If all three pipes are opened at the same time, how long will it take to fill the pool?
In an hour, the first pipe can fill up 1/8 of the pool
In an hour, the second pipe can fill up 1/12 of the pool
In an hour, the third pipe can fill up 1/24 of the pool.
So, in an hour, the 3 pipes can fill up 1/8 +1/12 + 1/24 = 6/48 + 4/48 + 2/48 = 11/48 of the pool.
It will take the 3 pipes 1 : 11/48 = 48/11 hours to fill the pool.

kareem sells homegrown vegetables at the farmers market. She charges three dollars per pound of tomatoes and four dollars per pound of asparagus. Kareem made $180 and sold 28 pounds of tomatoes. How many pounds of asparagus did kareem sell?
please help
Answer:
23.35 pounds.Step-by-step explanation:
If Kareem sold 28 pounds of tomatoes, then we first need to figure out, how much money she earned from that. That will be done by multiplying.
Since 1pound=$3
28x3=?
20x3=60
8x3=27
60+27=87
So, Kareem earned 87 dollars from selling all the tomatoes.
Now, we have to find out, how many dollars did the asparagus make for her.
That will be done by subtracting 180 by 87
180-87=?
180-80=100
100-7=93
So, the money that Kareem earned from selling all the Asparagus was $93.
Now, we have to find the amount of pounds of Asparagus did Kareem sell.
That will be done by dividing 4 by 93. (You can already say that the answer will be in decimals, or with a remainder)
93/4=
80/4=20
13/4=3.25 (since, 4x3=12, 4 parts of 100=25%, that's why that's the answer)
20+3.25=23.25
So, Kareem sold 23.25 pounds of Asparagus.ANSWERS INFO:
Kareem earned: $180
Kareem sold pounds of tomatoes : 28
Kareem sold pounds of Asparagus : 23.25
Thanks!

Answer:
$1.50
Step-by-step explanation:
if one pound of boysenberries is $3, and we want to find the price of half a pound, simply divide 3 in half.
3/2 = 1.50
so, 1/2 lb of boysenberries is $1.50.
Answer:
she buys half a pound and we need to know how much she spends.
If 1 full pound is $3, we need to half that.

The graph of a quadratic function has x-intercepts at x = 3 and x = -5. It passes through the point
(1,-12). Determine the equaiton of the quadratic function.
The quadratic function that has x-intercepts at x = 3, and x = -5 that
passes through the point (1, -12) is f(x) = x² + 2·x - 15.
How can the required quadratic function be found?The intercepts of the graph of the quadratic function are x = 3 and x = -5
The point through which graph passes is (1, -12)
Required:
The equation of the quadratic function.
Solution:
Given that the intercepts are x = 3, and x = -5, we have;
x = 3, and x = -5 are the zeros of the quadratic function, which gives;
Factors of the quadratic function are; (x - 3) and (x + 5)
From which we have;
(x - 3) × (x + 5) = x² + 2·x - 15 is a factor of the quadratic function
When x = 1, we have;
1² + 2 × 1 - 15 = -12
Therefore, the point (1, -12) is a point on the quadratic function x² + 2·x -
15 that has intercepts at x = 3, and x = -5
The equation of the quadratic function is therefore;
