Question

Which of the following trigonometric ratios have the value equal to 0.5?

• A. Sin 30°
• B. Cos 30°
• C. Sin 60°
• D. Cos 60°

Answer 1

Answer: (A), (D)

The correct options are
A Sin 30°
D Cos 60°

We know that, the value of
$Sin30°=\frac{1}{2}Cos30°=\frac{\sqrt{3}}{2}Sin60°=\frac{\sqrt{3}}{2}Cos60°=\frac{1}{2}$

So, Sin 30° and Cos 60° has the value equal to 0.5.
