Find `theta`; if `sin(theta + 36^@) = cos theta`; where ` theta + 36` is an acute angle.

Dind theta; if sin(theta+36^(@))=cos theta; where theta+36 is an acute angle.

Find theta , " if " sin 5 theta = cos 4 theta : where 5 theta and 4 theta are acute angles.

If sin (theta+36^(@)) =cos theta find the value theta

Evaluate sin^2 theta- cos^2 theta. " If " sqrt3 tan theta = 3 sin theta, theta ne 0 and theta is an acute angle.

Evaluate sin^2 theta - cos^2 theta , if sqrt3 tan theta = 3 sin theta , theta = 0 and theta is an acute angle.

If Cos 3 theta = Sin(theta - 34^(@)) , then the value of theta as an acute angle is :

If tan 2 theta = cot 4 theta where 2 theta and 4 theta are acute angles. Find theta

If cos 3 theta = sin ( theta - 6^@ ) where 3 theta and theta - 6^@ are acute angles, find the value of theta .
