Answer:

x=12

Explanation:

Hello There!

So first things first, the angle labeled 4x+17 and the blank interior angle are vertical angles meaning that they are congruent

So now we can solve for x

Remember all of the angles in a triangle add up to equal 180 so

180 = x + 23 + 80 + 4x + 17

step 1 combine like terms

4x+x=5x

23+17+80=120

now we have

180=120+5x

step 2 subtract 120 from each side

180-120=60

now we have

60=5x

step 3 divide each side by 5

60/5=12

we're left with x=12
