Question

In a triangle, the measures of the angles are x, x + 20, and 2x. What is the value of x?
​

Answer 1

Answer:
Sides of a triangle are x,x+20 and 2x
Sum of all the angles of a triangle=180 deg.
x+x+20+2x=180
4x=180-20
x=160/4
x=40

Answer 2

Side 1 of triangle - x
2nd side - x+20
3rd side - 2x

We know that sum of all 3 angles
=180 degree (angle sun property)

x+x+20+2x=180
4x+20=180
4x=180-20
4x= 160
x= 160/4 = 40

Therefore value of x=40 degree

Then , x=40 degree
x+20=40+20=60 degree
2x=2*40=80 degree
