Thread: Whoa I Def Need Help

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

What are you double posting? I already answered your question here: http://www.mathhelpforum.com/math-he...ct-values.html

Please do not double post.
