Q. 24.5( 13 Votes )

The angles of a triangle are in the ratio 2:3:4. Find the angles.

Answer :

40°, 60°, 80°


Let the angles of triangle are 2a, 3a and 4a.


Therefore,


2a + 3a + 4a = 180°[Sum of angles]


9a = 180°


a = 20°


Angles of triangle are,


2a = 2 × 20° = 40°


3a = 3 × 20° = 60°


4a = 4 × 20° = 80°
