Question

6.If sin = 0.8829, then the approximate measure of between 0° to 360° is _______

A. 62°, 28° B. 62°, 118°   C. 62°, -28°   D. 62°, 208°

Answer 1

Given that, sin(θ) = 0.8829

i.e. θ = sin^{-1_{​​​​​​}}(0.8829)

i.e. θ ≈ 62°

Now as 0° ≤ θ ≤ 360°, so we also have,

θ = (180° - 62°) = 118°

.

So option B is correct.
