A. 10
B. 5
C. 20
D. 15

Answer 1

Well all of those equations together have to equal to 180 degrees

Answer 2

well, that doesnt help me much.=/

Answer 3

Lol it will look because all of those together have to equal 180 you can make a bug equation see:
7x + 3x - 5 + 8x +5 = 180

Answer 4

*big equation now keep all the x's on one and move everything else to the otherwise what's ur simplified equation

Answer 5

oh! okay so its ten? ... i didnt understand how to put the 7x into the equation i was drawing a blank. now i just feel stupid.

Answer 6

Yup it's ten and that's okay you just Ned to stare at it until something happened on your mind lol

Answer 7

*something happens

Answer 8

okay, so i have a similar question and it needs the value of x again, the two angles it gives me is 2x and 4x how do i put that into an equation to figure out the value of x? (im horrible at math online school doesnt teach its just gives you assignments)

Answer 9

Do u have a diagram?

Answer 11

Oh simple the two angles have to make 90 degrees so add the two together to have them equal 90

Answer 12

2x + 4x = 90

Answer 13

okay, so it just needs to equal the size of the angle, which would make it 15?

Answer 14

Yup that's correct.
