Hope this helps uh✌

Answer 2

We have:

$\sin A$ = $\cos A$, where $\theta$ is an acute angle

We have to find, the value of $\theta$.

Solution:

∴ $\sin A$ = $\cos A$

⇒ $\sin A$ = $\sin (90- A)$ [ ∵ $\cos A$ = $\sin (90- A)$]

⇒ A = 90° - A

⇒ A + A = 90°

⇒ 2A= 90°  

⇒ A = 45°  

Thus, the required "option b) 45°"  is the correct.
