Question

Solve for x no work needed

Answer 1

`\huge\boxed{82 \textdegree}`

Explanation:

We know that all angles in a triangle will add up to 180°. Since we know the measure of all 3 angles, we can create this equation:

`31+x+(x-15) = 180`

Let's solve for x.

Combine like terms:

`31+2x-15=180`

Add 15 to both sides:

`31+2x=195`

Subtract 31 from both sides:

`2x=164`

Divide both sides by 2:

`x= 82`

So x is 82°.
