Hey! Please find the value of x, so I can find the value of angle H! Thanks
o-na [289]
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!

Why might soft drink companies be interested in the dimensions that give the minimum surface area?
12345 [234]
When surface area is minimized, that means the less material companies would have to use for the can. Companies can spend less money on aluminum for the can and still hold the same amount of that beverage inside the can.

A printing company charges $42 plus $0.05 per page. Another company just charges $0.08 per page. How many pages are in an order
Nookie1986 [14]
There should be 1,400 pages in an order that costs the same for both companies.

Let x be the unknown number of pages.

1st Company = 42 + 0.05x
2nd Company = 0.08x

0.08x = 42 + 0.05x
0.08x - 0.05x = 42
0.03x = 42
0.03x / 0.03 = 42 / 0.03
x = 1400 pages

To check

0.08x = 42 + 0.05x
0.08 (1400) = 42 + (0.05 * 1400)
112 = 42 + 70
112 = 112
