Step-by-step explanation:
first, the other 2 angles in the triangle must be equal.
and they must both be complementary to 180 degrees for the 108 degree angle.
180 - 108 = 72 degrees.
so, we have 72, 72 and m degrees as degrees in the triangle.
the sum of all the angles in a triangle is always 180 degrees.
72 + 72 + m = 180
144 + m = 180
m = 36 degrees
