1. ## 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:

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

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