Question

if fig,∠PQR=90°,∠PQS=90°,∠PRQ=∝ and ∠ QPS=θ write the following trigonometric ratios. a)Cosθ. b)sin(90-∝). c)tan ∝. tan(90-θ)​

Answer 1

Answer:

Step-by-step explanation:

a) cos theta = PQ/ PS

b) sin ( 90 - α) = sin α = PQ/ OR

c) tan α . tan ( 90- theta ) = PQ / QR × tan theta = PQ / QR × QS / PQ

( Numerator PQ and Denominator PQ are cancelled ) = QS / QR is the answer.
