Answer:

[tex]x = 50[/tex]

Step-by-step explanation:

[tex]x + x + (2x - 20) = 180 \\ x + x + 2x - 20 = 180 \\ 4x - 20 = 180 \\ 4x = 180 + 20 \\ 4x = 200 \\ \\ x = \frac{200}{4} \\ \\ x = 50[/tex]

[tex]2x - 20 \\ 2(50) - 20 \\ 100 - 20 = 80[/tex]

The value of x in the triangle is 50

The angles in a triangle add up to 180.

So, we have:

x + x + 2x - 20 = 180

Add 20 to both sides

x + x + 2x = 200

Evaluate the like terms

4x =200

Divide both sides by 4

x =50

Hence, the value of x in the triangle is 50
