Two angles of a riangle are equal and the third angle is gratehr than each one of them by 18 degree find the angles

Let the measure of each equal angle be x.

Then the measure of third angle = x + 18°

We know that sum of all angles of a Δ is 180°

∴ Measure of each of the equal angle is 54°.

Measure of greater angle = 54° + 18° = 72°
