Question

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

2 Answer

  • 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:

    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°.
