Question

If the sin 30° = one half, then which statement is true?

cos 150° = 0, because the angles are supplements
cos 60° = one half, because the angles are complements
cos 150° = 1, because the angles are supplements
cos 60° = 0, because the angles are complements

Answer 2

The correct state about Sin 30⁰ which is equal to one half is, cos 60° = one half, because the angles are complementary.

What are complementarty angles?

Complementary angles are the angles that sum up to 90 degrees.

A complementary angle of 30⁰  is calculated as follows;

θ = 90⁰ - 30⁰ = 60⁰

Sin 30⁰ = ¹/₂ = Cos 60 = ¹/₂

Thus, the correct state about Sin 30⁰ which is equal to one half is, cos 60° = one half, because the angles are complementary.
