If the cos 42° = one half, then the sin 48° = _____.

two thirds, because the angles are complementary
2 over 1, because the angles are supplementary
one half, because the angles are complementary
1, because the angles are complementary

Respuesta :

lucic

one half, because the angles are complementary

Step-by-step explanation:

Complementary angles add up to 90°.

Hence, 42° is complementary to 48°

cosine of an angle =adjacent/hypotenuse

Sine of an angle= opposite/hypotenuse

Cos x= Sin (90-x)

Putting x=42°

Cos 42° =Sin (90-42)

Cos 42°=Sin 48° =1/2
