Well this is simple. First you have to know what type of formula your gonna be using. Which means you can’t use a squared+b squared=c squared.
So first you look for what angles you do have and that’s a 90 degree angle. Next you look for other givens like the two side are even. Now you know it’s a Isosceles triangle. So since we know we have 90 degree angel already and there can only be 90 left becasue it’s only 180 degrees in a triangle and 90+90 makes 180. You divid 90 by 2 and it gives you 45 and that’s the other two angles. Anther name for the triangle is 45,45,90 it’s called for special triangles when using square root.
