LMN... Three letters, so three points, so three sides. Only one shape with three sides right? A triangle.

The total the angles in a triangle equals 180. 

If you have two angles and all equal 180 when said and done, what should you do?

Omg, I read this wrong, I'm sorry. They are side measurements. So they give two sides and one angle (90). I gtg soon, but follow this.

You need side LN, which is the hypotenuse. Use Pythagorean Theorm. Once you find that side, use ratios

Like

90.                                    X
----                     =           -------
Hypotenuse.                  76

Then repeat. I will help you when I get home. Sorry for the vague help
