<u>Answer-</u>

<u>Solution-</u>
We know that arc length is the product of radius and central angle in radian.
i.e 
Here,

So,




The answer is probably -78*degree sign*C.
Answer: On a number line, 0 is in the middle, to the right , 7 is 7 spaces away from 0
F(2) = 8
if x = 2 then you plug in 2 for x making the equation 3(2) + 2 which equals 8
Angle 1 = 130°
Angle 2 = 124°
Angle 3 = 56°
Angle 4 = 52°
Angle 5 = 72°
Angle 6 = 94°
I primarily used the triangles to get my answers. Remember the angles in a triangle add up to 180°.
