Question

If sin A =cos A, then angle A=

Answer 1

Answer:

sin A = cos A

it can be written as

sin A = sin(90-A)

A = 90-A

2A= 90

A= 45 degrees .

Answer 2

Answer:

45°

Step-by-step explanation:

We know that sinA = cos(90°-A)

As sinA = cosA

Therefore, A = (90°-A)

=> A + A = 90°

=> 2A =90°

=> A = 90°/2

=> A = 45°
