Answer 5

let m<I = x
if m<G is 8 more than m<I then naturally m<G = x + 8
if m<H is 20 more than m<G then naturally m<H = x + 8 + 20

since all the angles in a triangle sum up to 180, simply sum x + x + 8 + x + 8 + 20 = 180 to solve for x. that gives m<I, and from there you can go back and calculate what m<G and m<H are

Answer 8

I did that and I got 3x=138

Answer 9

good, now divide both sides by 3 to isolate x

Answer 10

X=46?

Answer 11

good, so that's your m<I

then m<G is therefore 46 + 8
and m<H is 46 + 8 + 20

Answer 12

Ok

Answer 13

Wait, the equation is wrong! I got 3x=148!
