Step-by-step explanation:
heheheh I do math lol
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
Answer:
37
Step-by-step explanation:
Its letter D
7(19)-21 (x=19)
133-21=112 (RZ)
