T # 8

If x*sin60°*tan30°=(sin45°*cot45°)/(cos30°*cosec60°), find x.

for this i got every part easily cept sin 45 because it equals a long decimal so it didnt seem right but i got 1.414

Re: Trigonometry

Hi anonimnystefy,  Shivamcoder3013, Stormtangent, and fusilli_jerry89,

The solutions #7 and #8 are correct. Excellent!

#9. If two angles of on the base of a triangle are 22.5 degrees and 112.5 degrees, then what is the ratio of the height of the triangle to length of the base?

I have the result, but I do not yet know how to get it.
