I am struggling today with my homework,
Find the Exact values of Tan 165 degrees ( 165 is the sum of two special angles) that is 135 degress and 30 degrees
Ok for far i have
Tan ((-Sqrt2)/2+(sqrt3)/2)=((Tan -Sqrt2/2) + (Tan sqrt3/2))/1 +(Tan -sqrt2/2)(tan Sqrt3/2)
135 is in the 2nd quadrant and tan is negative so it will be -Sqrt2/2 and 30 degrees is a 1st quadrant angle and tan is positive so its sqrt3/2
and now im stuck on this problem

Alternatively, tan(165) = - tan(15) = - tan(45 - 30) .....
