Hi, I have this really annoying problem in Geometry..
There's this triangle:
BD is perpendicular to AC(Both sides of <D form 90 degrees)
ABC is a right triangle, <B=90
<A = alpha
The question is:
Express using alpha the following angles:
For example is alpha was <C + <C then you'd express using alpha the angle <C by writing <C = 1/2alpha
This should be solved using very basic right triangle rules, but I don't know what to do.
I need this for tomorrow's homework =/
Thanks to all helpers
