Find the number of degrees in the measure of the vertex angle of an isosceles triangle if each base angle measures 36 degrees

The vertex angle measures 180 degrees

Step-by-step explanation:

Since this isosceles triangle gives us the base angles, we know that thee are two of that congruent angle. So the first two angles are 36 degrees. This means that since the angle measures all add up to 180 degrees, we can use subtraction to find the third angle, or the vertex angle.

36 + 36 = 72

180 - 72 = 108
