If three angles of a triangle are in a ratio 2:3:4, the angles of the triangle are:

(a) 30:, 60:, 90: (b) 40:, 50:, 90: (c) 40:, 60:, 80:.​

Answer 1

Answer:

Let the angles be 2x , 3x and 4x

by angle sum property of triangle

2x + 3x + 4x = 180°

9x = 180°

x= 20°

Therefore, The angles are

2x= 40°

3x= 60°

4x= 80°

Therefore option (C)
