Question 10:
20
10
Step-by-step explanation:
Since the circle is centered at the origin, we can use the equations
x² + y² = r²
x = r cos θ
y = r sin θ
We know y = 8 and r = 10. Solving for x
x² + 8² = 10²
x = 6
From this equation:
x = r cos θ
6 = 10 cos θ
cos θ = 6/10 = 0.6
112 is the answer. I am not really sure what the parenthesis are for, but those answers in the parenthesis are wrong.
