if sin theta = cos theta then theta =?​

Answer 1

Answer:

45

Step-by-step explanation:

sin 45 = cos 45 = 1/√2

hopefully it will help

Answer 2

Answer:

sin theta= cos theta

From sin² theta + cos² theta= 1,

sin² theta + sin² theta= 1

2sin² theta= 1

sin² theta= 1/2

sin theta=1/√2

sin theta= sin 45°

theta= 45°
