Question

if angle are in ratio 2:3:4determine three angles

Answer 1

Let angles are 2x, 3x and 4x



As we know that the sum of all angles of a triangle is 180



2x + 3x + 4x = 180

9x = 180

$x = \frac{180}{9} \\ \\ x = 20$





Hence, Angles are


2x = 2(20) => 40°
3x = 3(20) => 60°
4x = 4(20) => 80°

Answer 2

${ hey dear }$


angles are in the ratio = 2x, 3x , 4x



sum of all angle = 180


2x + 3x + 4x. = 180


9x = 180

x = 180 / 9

x = 20


hence angle are

2x = 2 *20 = 40

3x = 3 * 20 = 60

4x = 4 * 20 = 80
