Help please.

Step-by-step explanation:

so the probably seems impossible b/c there is some "implied" knowledge. You are supposed to remember that interior angles of a triangle add up to 180 °.   Which I bet you knew.. .huh

so let's put that knowledge to work to help us solve this

we can say that all of the angles add up to 180 like this:

180 = (x-4) + (11x-11) + (x+13)

see? now group all the like terms, that is, put the x'es together & the numbers

180 = 13x -2

see?  I just grouped the x terms and the constant terms, now move the 2 arcoss the equal sign to the other side, by adding 2 to both sides

182 = 13x

see?  now divide both sides by 3  :)

14 = x  

now we know what x is so plug that into the expression for the C angle

∠C = x-4

∠C = 14-4

∠C = 10 °

there you go.   :)

best of luck, just leave a message in the comments if you have more questions  , I'll see it there  :)

8

step-by-step explanation:

to find the amount of gift bags to use all the supplies, find the gcf or greatest common factor. this is the largest number which multiplies evenly into each term.

48 has factors: 1, 2, 3, 4, 6, 8, 12. 16, 24, 48

80 has factors: 1, 2, 4, 5, 8, 10, 16, 20, 40, 80

64 has factors: 1, 2, 4, 8, 8, 16, 32, 64

the highest number factor they all share in common is 8. this means there will be 8 bags with 6 pencils, 10 markers, and 8 stickers in each bag.

with btw u said 100pts but it clearly says

i answerd and just got 10pts

no hate
