Question

exit ticket directions: point b is between points a and c. line segment ac is 29 units long. line segment bc is 8 units long. how long is line segment ab? show your work.

Explanation:

Step1: Set up equation

Since $AB + BC=AC$, let $AB = x$, $BC = 8$ and $AC = 29$, we have the equation $x + 8=29$.

Step2: Solve for x

Subtract 8 from both sides of the equation: $x=29 - 8$.

Step3: Calculate result

$x = 21$.

Answer:

21
