Answer:
Step-by-step explanation:
<u>I'm assuming the angles are in degrees.</u>
The answer is D because u can find the radius from the number
4 cups of pecans = 5 cups of walnuts
x cups of pecans = 8 cups of walnuts
CROSS MULTIPLY
4*8 =5x
5x = 32
DIVIDE BOTH SIDES BY 5
5x/5 = 32/5
x=6.4
Therefore, 6.4 cups of pecans would be added to 8 cups of walnuts
-(36 degrees) =
-0.628318531 radians
hope this helps you
