Question

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

Answer 1

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

Answer:

B) sec 28

Step-by-step 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°.
