Question

the angle of a triangle are in the ratio 2:3:4 the largest angle of the triangle is​

Answer 1

the angle of a triangle are in the ratio 2:3:4

largest angle of the triangle = 80°

Answer 2

Sum of all angles of a triangle is 180°

2x+3x+4x = 180°

9x = 180°

x = 180°/9

= 20°

Angle 1 = 2x = 2*20° = 40°

Angle 2 = 3x = 3*20° = 60°

Angle 3 = 4x = 4*20° = 80°

Hence,

Angel 3 is the largest angle.
