Thread: Question with special angles and Trig Identities

Hello again Everyone,

I had a question I was able to finally solve by myself but I was wondering if the following method is correct.

The problem is,

How I solved it...


Which equals 1.732

Since I knew the question asked about special triangles I did the following
tan(30°) = 0.57735
tan(45°) = 1
tan(60°) = 1.73205
Therefore = 60°

Is this an acceptable method or the "right" method?

It is definitely a method. I wouldn't necessarily say it is the most direct or elegant method.

YES! I finally found this web page! I’ve been looking just for this article for so long!!
