Question

if sin theta-cos theta=0 ,0<theta<90,find the value of theta​

Answer 1

Explanation:

sin theta - cos theta = 0

sin theta = cos theta

theta = 45°

because values of sin 45° and cos 45° are same, i.e. 1/root2

Answer 2

given that : sin theta= cos theta also 0°is less than theta and 90° is greater than theta...

now, accordingly to trigonometry table-

sin45° = cos45° i.e, 1/√2

so, value of theta = 45°
