Question

can 3x,2x,4x, be the angles of a triangle?find value of x
​

Answer 1

sum of all angle of a triangle = 180°

3x+2x+4x=180

9x=180

x=180/9

x=20

angles of the triangle are

1) 3x

3*20=60°

2) 2x

2*20=40°

3) 4x

4*20=80°

60°+40°+80°

=180°

hence 3x,2x,4x, can be a triangle...

Answer 2

Answer:

yes and x=20

Step-by-step explanation:

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

9x=180

x=180/9

x=20

yes they can be angles of triangle since a triangle has 3 angles
