Sine is opposite over hypotenuse
Cosine is adjacent over hypotenuse
Tangent is opposite over adjacent
In this context, opposite means the side opposite of the angle. Adjacent means the side that is touching the angle. And the hypotenuse is the longest side, which is usually visually obvious.
3.) tan(25) = x/31
Use a calculator for tan(25), then multiply both sides by 31 to get your x value.
x = 14.5
4.) cos(48) = 17/x
Use a calc to do 17/cos(48) to get the x value
x = 25.4
5.) sin(theta) = 17/18
Divide 17/18, then take the inverse sine of both sides with a calculator to get the theta value
theta = 70.8 degrees
6.) tan(theta) = 31/42
Divide 31/42, then take the inverse tangent of both sides with a calc.
theta = 36.4 degrees
7.) Your best bet is to draw a picture. For my case, Im going to imagine it. The angle is 35 degrees and the hypotenuse is 300 feet. The question is asking for the opposite of the angle. This calls for sine.
sin(35) = x/300
x = 172.1 feet

What is the value of c in the equation below?
===============================================
Explanation:
We'll use the rule
x^y*x^z = x^(y+z)
This says that when we multiply exponential expressions with the same base, we add the exponents. In this case, the base is 2 so x = 2.
The exponents we're adding are -4 and 2
So,
2^(-4)*2^2 = 2^(-4+2) = 2^(-2)
This matches up with the a^b to show that a = 2 and b = -2
Furthermore, we'll use the rule that x^(-y) = 1/(x^y) to go from 2^(-2) to 1/(2^2) = 1/4 which is the value of c.

How you find the circumference is easy.
The formula is 2πr, meaning you multiply 2 times pi (3.14) times the radius (20 m)
2 x 3.14 =
6.28 x 20 =
Circumference: 125.6
The second problem is easier than the last.
Instead of multiplying by 2, you'll only multiply 3.14 (pi) times 90.
3.14 x 90 =

what makes an equation proportional
Answer:
(Some textbooks describe a proportional relationship by saying that " y varies proportionally with x " or that " y is directly proportional to x .") ... This means that as x increases, y increases and as x decreases, y decreases-and that the ratio between them always stays the same.

What is the radius of a circle whose equation is -10xt6y+18-0?
O 2 units
O 4 units
O8 units
O 16 units
Answer:
Radius, r = 4 units
Step-by-step explanation:
The equation of circle is given by :
[tex]x^2+y^2-10x+6y+18=0[/tex]
We need to find the radius of the circle.
The general equation of a circle is given by :
[tex](x-h)^2+(y-k)^2=r^2[/tex] ....(1)
We can rearrange the above equation in terms of the given equation as follows :
[tex]x^2+y^2-10x+6y+18-25-9+25+9=0\\\\(x^2-10x+25)+(y^2+6y+9)+18-25-9=0\\\\(x-5)^2+(y-(-3))^2=(4)^2[/tex]
On comparing the above equation with equation (1)
h = 5, k = -3 and r = 4
So, the radius of the circle is 4 units.
