if ac = 23 and bc = 19, find ab.
if ac = 23 and bc = 19, find ab.
Answer
Explanation:
Step1: Identify segment - length relationship
From the line - segment diagram, we know that $AC=AB + BC$.
Step2: Solve for AB
We can rewrite the formula as $AB=AC - BC$. Substitute $AC = 23$ and $BC = 19$ into the formula. So, $AB=23−19$.
Step3: Calculate the result
$AB = 4$.
Answer:
4
