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!

Answer:
41
Step-by-step explanation:
So basically you need to use the pythagorean thrm. Essentially, the diagonal and the width and length create a triangle, the diagonal being the hypothenuse. So the formula goes as ![\sqrt[]{a^{2} +b^{2} }](https://tex.z-dn.net/?f=%5Csqrt%5B%5D%7Ba%5E%7B2%7D%20%2Bb%5E%7B2%7D%20%7D)
. the variable "a" being the length and the variable "b" being the width. So plug it in and there you have your answer!
The answer is choice D because if you combine the like terms, you get 15-23i
i hope that helps!!!!
