Answer: x=32

Step-by-step explanation:

The angles in a triangle add up to 180 degrees.

Since we know a=10 the other two angles must add up to 170 degrees.

[tex]2x+3x=170[/tex]

We can now solve for x

[tex]2x+3x=170\\5x=170\\\frac{5x}{5} =\frac{170}{5}\\x=34[/tex]

We can sub in x to both angles to see if they angles add up to 180

[tex]2(34)+3(34)+10=180\\68+102+10=180\\180=180[/tex]
