Question

Which trigonometric value is equal to cos 62°? A) cos 28° B) sec 28° C) sin 28° D) tan 28°

Answer 1

B) sec 28

Explanation:

The solution is found by applying the definition of complementary trig functions:

Cos (&Theta) = sin (90°-&Theta)

cos (62°) = sin (90°-62°)

Therefore the solution is sin 28°.

Answer 2

The solution is found by applying the definition of complementary trig functions:

Cos (&Theta) = sin (90°-&Theta)

cos (62°) = sin (90°-62°)

Therefore the solution is sin 28°.
