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: Recall segment - addition postulate

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

Step2: Rearrange the formula to solve for $GH$

$GH=FI - FG - HI$.

Step3: Substitute the given values

Given $FG = 2$, $FI = 7$, and $HI = 1$. Then $GH=7-2 - 1$.

Step4: Calculate the value of $GH$

$7-2 - 1=4$.

Answer:

4 units
