    Help finding the following signs of this triangle...

    Sorry, I meant "sides" of this triangle...

    Hey everyone,

    Can someone help me with what formulas I need to used to find the "y" and the "x2" sides of the triangle that I have attached to this post?

    I'd greatly appreciate it...

    Thanks!

    Use the small right triangle:

    y=5\cdot \sin(50^\circ)

    x_2= 5 \cdot \cos(50^\circ)
