Question

3) If theta= 45° then cos theta= sin theta = ?​

Answer 1

Answer:

1 divide by under root 2

is the right ans

Answer 2

Answer:

$\cos(theta) = \sin(theta) = \frac{1}{ \sqrt{2} }$

Step-by-step explanation:

If theta = 45°

cos theta = cos 45° = 1/root 2

sin theta = sin 45° = 1/ root 2
