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

if fg = 2 units, fi = 7 units, and hi = 1 unit, what is gh? 3 units 4 units 5 units 6 units
Answer
Explanation:
Step1: Identify the relationship
We know that $FI=FG + GH+HI$.
Step2: Rearrange the formula for $GH$
$GH=FI - FG - HI$.
Step3: Substitute the given values
$GH = 7-2 - 1$.
Step4: Calculate the result
$GH=4$.
Answer:
4 units
