Hey there! :D

The congruence marks on the trapezoid make the angles congruent. This makes opposite angles supplementary. (Because all the angles in a trapezoid add up to 360 degrees)

12x-31+6x-5= 180

18x-36= 180

Add 36 to both sides. 

18x= 216 

Divide both sides by 18. 

x= 12

You can just plug that in to find m<H. 

6x-5

6(12)-5

72-5

m<H= 67

I hope this helps!
