Question

solve for x no work needed

Answer 1

Answer:

$\huge\boxed{82 \textdegree}$

Step-by-step 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°.
