Question

triangle is 3:4:2 If ratio of 3 angle of a
Find all angles of the triangle.​

Answer 1

Answer:

180× 3/9=60

180 × 4/9=80

180 × 2/9=40

Answer 2

Answer:

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

We know that sum of all angles of a triangle is 180°.

therefore,

3x + 4x + 2x = 180°

9x = 180°

x = 180° / 9

x = 20°

so, 3x = 3 × 20° = 60°

4x = 4 × 20° = 80°

2x = 2 × 20° = 40°
