Each of the two angles of the triangle is 3/4th of the third angle. Find the angles.

Answer»

Let the THIRD ANGLE be x

Then the other two angles = 3x/4

By angle sum PROPERTY of a triangle,

3x/4 + 3x/4 + x = 180°

→ 3x/2 + x = 180°

5X = 360°

→ x = 72°

The other two angles hence would be 3 × 72/4 = 54°
