Answer 1

This is an isosceles triangle. Whenever you have an isosceles triangle, that means the base angles are congruent.

Answer 2

So you know the other base angle (angle R) has a measure of 37 degrees as well

Answer 3

You know two of the angles, and you know that the sum of all the angles is 180 degrees for any triangle. This means you can figure out the third angle.

Answer 4

Yes, what Jabberwock said: the total measure of a triangle is 180 degrees
