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
