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 three times nbsp the measure of either of the other two​ angles, find the measure of each angle of the triangle.​ (Recall that the sum of the measures of the angles of a triangle is​ 180°.)

  1. the angles sum to 180​°, so if the two equal angles are x​°, we have
    2x + (3x+45) = 180
    Find x, then use that to give the angles.
