Question

Find sin (90° - Φ),cosΦ and tanΦ​

Answer 1

Answer:

This is the answer bro

Its a bit tricky in judging that sin(90-Θ) is cos Θ

Answer 2

Answer:

a² + b² = c²

PQ² + 12² = 15²

PQ² + 144 = 225

PQ² = 81

PQ = 9

Find sin(90-∅), cos∅, and tan∅

sin(90-∅) = sin R

sin R = 9/15

sin R = 3/5

cos ∅ = 9/15

cos ∅ = 3/5

tan∅ = 12/9

tan∅ = 4/3
