Question

If sin θ = cos θ, find the value of θ.​

Answer 1

SOLUTION

$sin \theta = cos \theta \\ = > sin \theta = sin \:(90 - \theta) \\ = > \theta = 90 - \theta \\ = > 2 \theta = 90 \\ = > \theta = \frac{90}{2} \\ \\ = > \theta = 45 \degree$

hope it helps ☺️

Answer 2

Step-by-step explanation:

Sin x=sin(90-x)

So x=45
