Question

if sin theta=cos(theta-6),find the value of theta

Answer 1

Answer:

sinФ = cos(Ф - 6)

cos(90° - Ф) = cos(Ф - 6)

Comparing both sides

90° - Ф = Ф - 6

2Ф = 96

Ф = 48°

Answer 2

sinthetha=cos (theta-6)

by using complemetry angles

sin(90-theta)=cos theta

sin(90-theta)=cos (theta -6)

cos(90-theta)=cos(theta-6)

by cancelling

90-theta=theta-6

90+6=theta+theta

96=2theta

96/2=theta

48= theta
