The calculated length of the segment BA is 13.3

How to determine the length of the segment BA

From the question, we have the following parameters that can be used in our computation:

The right triangle

Also, we have

AD = 8, DC = 6, and AC = 10

Start by calculating BD using

BD = AD²/DC

So, we have

BD = 8²/6

BD = 10.67

Next, we have

AB² = BC² - AC²

AB² = (10.67 + 6)² - 10²

AB² = 177.89

Evaluate

AB = 13.3

Hence, the length of the segment BA is 13.3
