Answer:

$x=-\frac{41}{6}$

Step-by-step explanation:

Pay attention to the two tick marks. This indicates that those sides are congruent to each other and so will the angles on the bottom and top. Therefore, we can set up the equation $137+2(-3x+1)=180$ and solve for x:

$137+2(-3x+1)=180$

$137+(-6x+2)=180$

$137-6x+2=180$

$139-6x=180$

$-6x=41$

$x=-\frac{41}{6}$
