Question

if sinA = cosA , then find the value of A

Answer 1

Answer: 45 °

Step-by-step explanation:

It os only possible at angle A is equal to 45 degree

As sin 45° = 1/ root 2

And cos 45° = 1/ root 2

Answer 2

$\sin(a) = \cos(a) \\ \sin(a) = \sin(90 - a) \\ on \: compairing \: \\ a = 90 - a \\ 2a = 90 \\ a = 45$
