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!

3x+12=39
Minors 12 on both side
3x=27
Divide 3 on both side
X=9
The answer is there with the attached peice
Given:
cost: 26,500
option: <u> 725</u>
total 27,225
tax (27,225 * 6%)<u> 1,633.50</u>
total 28,858.50
license & reg. fee <u> 50.00</u>
total cost 28,908.50 Choice D.
because its isosceles so 9+9=x²
and x equal
2√3
