Question 175050
The sum of the measure of the internal angles of a triangle is 180 degrees.

The equation that describes the situation in the problem is

x + x + (x + x -36) = 180 degrees where x is the measure of the angles with equal measure.

Adding like terms, we have 4x-36=180

So 4x=216 degrees

Solving for x, we have x = 216/4 = 54 degrees


So the measure of the 3 angles of the triangle are:

54, 54, 72 degrees

I hope that this helps.
