Question

find the measure ofthe angles of the triangle whenthe angles are in ratio 2:3:4

Answer 1

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

9x = 180

x = 20

2x = 2* 20
= 40

3x = 3*20
= 60

4x = 4*20
= 80

Answer 2

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

sum of all angles of a triangle is 180 degrees

therefore, 2x+3x+4x=180 (By angle measure prop)

9x=180

x=180/9=20 degrees

2x=2*20=40

3x=3*20=60

4x=4*20=80

the angles of the triangle are 40,60,80 degrees

thank youu :D
