Compound angles and exact values meed to he used

solve the following trig equation 4(I cos x I)+3=bcos2x if one of the roots is 5Pi/6

If sin(x) = 1/4 and x is in quadrantI,find the exact values of the expressions without solving for x. (a) sin(2x) (b) cos(2x) (c) tan(2x)

given cosθ=9/13 and sin θ negative, find θ in degrees between 0 and 360 degrees.

If 0 ≤ θ <2π, for what angles, θ, if any, is tan θ undefined?

Find area of quadrilateral ABCD with AB= 12cm, BC=10 cm, and CD=10 cm, angle B = 108 degres, and angle C = 132 degrees.

I have a right triangle, but i only have the measures for its angles (90,60,30) Is there any way for me to find the length of one side

sin(x) + sin(3x) = 4 sin(x) cos^2(x)

A) sin(2x) B)cos(2x) c) tan(2x)
