Question

find the value of a in the parallelogram

( a = 23 )
(type an integer or a decimal.)

( a b = 25.4 )
(type an integer or a decimal.)

( b c = square )
(type an integer or a decimal.)

Explanation:

Step1: Use the property of parallelogram (opposite sides are equal)

In a parallelogram, \(AB = CD\) and \(BC=AD\). We are given \(a = 23\).

Step2: Calculate the length of \(BC\)

Since \(BC=a - 3.5\), substitute \(a = 23\) into the formula.
\(BC=23- 3.5\)
\(BC = 19.5\)

Answer:

\(19.5\)
