Two angles of a triangle have the same measure. The measure of the third angle is 4°

Question

less than twice the measure of each of the equal angles. Given that the sum of the three
angles of a triangle is always 180°, find each of the three angles.

Answer 1

If there are two angles of measure x, then we have

x + x + 2x-4 = 180

Now just find x, and you're almost done.

Answer 2

each of the equal angles ---- x
third angle = 2x - 4

so : x + x + 2x-4 = 180
