Determine angle of triangle

WebIn triangle, um of interior angles = 180° 2y° + (3y + 15) ° + (2y + 25) ° = 180° Simplify. 2y + 3y + 2y + 15° + 25° = 180° 7y + 40° = 180° Subtract 40° on both sides. 7y + 40° – 40° = 180° – 40° 7y = 140° Divide both sides by 7. y = 140/7 y = 20° Substitute, 2y°= 2 (20) ° = 40° (3y + 15) ° = (3 x 20 + 15) ° = 75° (2y + 25) ° = (2 x 20 + 25) ° = 65° WebExpert Answer.
