Question

If sinA =cosA then what is the value of A​

Answer 1

Answer:

A = 45°

Step-by-step explanation:

SinA = CosA

$\sin(a) \div \cos(a) \: = 1 \\ \tan(a )\: = 1 \\ \tan(45) = 1 \\ a = 45 ^{o}$

We Know SinA / CosA = tanA

Now we have to check at which angle tan has value 1

tan45° = 1

a = 45 °
