Question

If H is the midpoint of GI, find GH.5x+2 9x - 10H

Answer 1

GH=17

1) Since GI is the midpoint then, it is fair to say that

GH is congruent to HI

So, 5x +2 =9x-10

5x+2-9x=9x-9x-10

-4x+2=-10

-4x+2-2=-10-2

-4x=-12

x=3

2) The question wants GH

Let's plug x =3

5(3) +2

15+2

17

GH=17
