Please help me solve this

x=38

Step-by-step explanation:

First, know that the sum of the angles in a triangle is 180.

Then, add the angles. 2x+38+x+x-10.

Make them equal to 180.

2x+38+x+x-10=180

Simplify.

4x+28=180

Subtract 28 from 180.

4x=152

Divide 4 from 152 to make x alone.

x=38

There you go!
