Find the value of tan(75°) using the identity for tan(A+B).

If cos2B = sin(1.5B + 20^o), then find the measure of 'B'.

The minimum value of 45 sin² θ + 28 cos² θ is

If √3cosec 2x = 2, then the value of x:

if 8 sin ² x + 3 cos ² x = 4  then find tan x

If cos 2A = 17, then find cos A

Find the value of:  (Sin² 60 ° X cos 30 ° X sec 60°)/tan 30°

Simplify the following trigonometric expression: 

15 cos 25° cosec 65° − 5 cot 80° cot 10°

If sin(3θ) = cos(2θ), then find the value of θ between 0 and 90 degrees.
