Question

sin theta = cos theta, find the value of theta.

solve this ​

Answer 1

Answer:

sin theta = cos theta....(given).

sin theta/cos theta= 1

tan theta=1....(Since sin theta/cos theta= tan theta).

But, tan 45 = 1

Therefore, theta = 45°

Answer 2

Answer:

sin theeta =cos theeta.

now it is well know that sin45=1/√2.

and cos45=1/√2.

since , theeta =45
