Question

7. If the angles of a triangle are in the ratio 2:4:3, then find the smallest angle.​

Answer 1

Let it be 2x, 3x, 4x

2x + 3x + 4x = 180

9x = 180

X = 180/9

x = 20

The smallest angle is 2x = 40

Answer 2

let= 2x; 4x; 3x

2x+4x+3x = 180 (angle sum property)

9x = 180

x = 20

2x= 40 degree

4x= 80 degree

3x = 60 degree

the smallest angle of triangle is 40 degree.
