Question

The flag of a country contains an isosceles triangle.​ (Recall that an isosceles triangle contains two angles with the same​ measure.) If the measure of the third angle of the triangle is 45​° more than the measure of either of the other two​ angles, find the measure of each angle of the triangle.​

Answer 1

The angles when added equal180
therefore:
x+x+(x+45)= 180
3x+45=180
3x=180-45
3x=135
x=135/3
x=45
therefor the angles
are 45, 45, 90 degrees
