if fg = 2 units, fi = 7 units, and hi = 1 unit, what is gh?\n3 units\n4 units\n5 units\n6 units

Explanation:

Step1: Identify the relationship

We know that $FI=FG + GH+HI$.

Step2: Rearrange the formula to find $GH$

$GH=FI - FG - HI$.

Step3: Substitute the given values

Given $FG = 2$ units, $FI = 7$ units, and $HI = 1$ unit. So $GH=7 - 2-1$.

Step4: Calculate the result

$GH = 4$ units.

Answer:

4 units
