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!

9 and 12 are slope-intercept form and 10 and 11 are point-slope form
I dont see anything u have to post on here whats the question you need help on ?
$3.17 Just turn the improper fraction into a mixed number which would be 3 1/6. Then, turn THAT into a decimal rounded to the nearest hundredth (pennies) which leads to $3.17.
Product means multiply so 2,681 times 4 = 10,724
