Question

if fg = 2 units, fi = 7 units, and hi = 1 unit, what is gh? 3 units 4 units 5 units 6 units

Explanation:

Step1: Find FH length

Since $FI = FH+HI$ and $FI = 7$ units, $HI = 1$ unit, then $FH=FI - HI$. So $FH = 7 - 1=6$ units.

Step2: Find GH length

Since $FH=FG + GH$ and $FG = 2$ units, $FH = 6$ units, then $GH=FH - FG$. So $GH = 6 - 2 = 4$ units.

Answer:

4 units
