Question:

If cos theta = sin theta where 0°<theta<90°

Then find the value of theta.

Answer:

The value of theta is 45°

Step-by-step explanation:

Given that

sin theta = cos theta

=>sin theta/ cos theta =1

We know that

sin theta/ cos theta= tan theta

=>tan theta= 1

= > tan theta= tan 45°

Comparing both the sides,

=> theta = 45°

Hence the value of theta is 45°
