Question

find the measure of $overline{hj}$.

ft

Explanation:

Step1: Use the segment addition postulate

By the segment addition postulate, \(HK = HJ+JK\). So, \(HJ=HK - JK\).

Step2: Substitute the given values

Given \(HK = 12.2\) ft and \(JK = 3.1\) ft. Then \(HJ=12.2−3.1\).

Step3: Calculate the result

\(12.2−3.1 = 9.1\)

Answer:

\(9.1\)
