Question

if sin A = cos A, 0< A <90 , then the angle A is equal what​

Answer 1

Answer: Angle A = 45 degrees

Step-by-step explanation:

As we know that the angle A lies between zero degrees and ninety degrees .

So, as the value of sin 45 degree is 1/√2  and also the value of cosine 45 degree is 1/√2.

Therefore, sine 45 degree and cos 45 degree are the only values that lies as per angle A condition in the question which justifies same angle i.e.-45 degree.

Therefore angle A = 45 degrees.
