Question

Angle's of a triangle ABC are in the ratio as angle A:B:C=2:4:3, then angle b is​

Answer 1

Answer:

In triangle ABC,

A:B:C = 2:4:3

Let the angle be x

Therefore,

Angle A + Angle B + Angle C =180°...sum of all angles of triangle in 180.

2x+4x+3x=180

9x=180

x=180/9

x=20°

Angle B =4x

Angle B = 4×20

Angle B= 80°

The measurement of Angle B is 80°
