Question

tutorial exercise
in the figure below, (overline{ac} parallel overline{de}), (bd) measures 7 m, (ad) measures 14 m, and (be) measures 8 m. find the length of (overline{bc}).

part 1 of 4
first, find the length of the segment (overline{ab}). substitute the values for (ad) and (db) and simplify.
(ab = ad + bd)
(ab = 14 + square)
(= square)

Explanation:

Step1: Identify the value of BD

We know BD measures 7 m, so we substitute BD = 7 into the formula.
\( AB = 14 + 7 \)

Step2: Calculate AB

Now we simplify the expression: \( 14 + 7 = 21 \)

Answer:

First blank: \( 7 \), Second blank: \( 21 \)
