Question

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

Answer 1

Step-by-step explanation:

Answer

The angles of triangle is x,x+20,2x

By angle sum property

Sum of all angles is equal to 180

x+x+20+2x=180

4x=180−20

4x=160

x=40

Answer 2

Answer:

x + (x + 20) + 2x = 180º. (sum of all angles in triangle is 180º)

x + x + 2x + 20 = 180º

4x + 20 = 180º

4x = 180 - 20

4x = 160º

x = 160/4

x = 40º

It take lot of effort
