What is the relationship between
the sine and cosine of complementary angles?
Explain your reasoning and use the relationship
to find cos 50 if sin 40 0.64.​

Respuesta :

Answer:

0.64

Step-by-step explanation:

Sine and cosine of angles are complimentary

This means

Sin x = Cos (90-x)

Cos x = sin (90 - x)

Therefore sin 40 = 0.64

Sin 40 = cos (90 - 40)

Sin 40 = cos 50

Cos 50 = 0.64
