Answer:

Algebra Review: x=-4, r =5

Step-by-step explanation:

Use distributive prop;

-3x-6=6

then add 6 to both sides to get x by itself

you get -3x=12

divide both sides by -3

you get x=-4

Again do distributive prop.

-12r+24=-36

trying to get r by itself, so subtract 24 on both sides

you get: -12r=-60

then divide -12 both sides to get r by itself  and you get r=5

Pythageron Theorem:

which is a^2+b^2=c^2

a=3, b=7 and c=C^2 (this is always the long side)

so then we get 3^2+7^2=c^2

9+49=c^2

opposite of sqaring is rooting

so we get sqare root of 58 or 7.6

I'm sorry I can't help you with the angles, I would suggest looking it up and Khan Acadamy is a good resource. Good Luck!
