Question

If FG = 2 units, FI = 7 units, and HI = 1 unit, what is GH?

3 units
4 units
5 units
6 units

Answer 1

4 units

Answer 2

than you check this image you see that the line of FI is formed from FG + GH + HI
yes ?

and you know that the length of FI = 7 units
the length of FG = 2 units and the length of HI = 1 unit

so now you can rewriting the above wrote equation in this form

7 = 2 + GH + 1 so from this do you can calculi the value of GH ?

Answer 3

you do 2-1 then we you get that value subratct it from 7

Answer 4

you do 2+1 = 3 and yes than subtract it from 7 and will get the right answer sure easy

Answer 5
