Problema Solution

the flag of a country contains an isosceles triangle. if the measure of the third angle of the triangle is 15 degrees more than three times the measure of either of the other two angles

Answer provided by our tutors

We will find the measures of the angles of this isosceles triangle.

x = the measure of each of the two equal angles

3x + 15 = the measure of the third angle

2x + 3x + 15 = 180

x = 33 degrees

3x + 15 = 3*33 + 15 = 114 degrees

The measures of the angles are 33 degrees and 114 degrees.
