Question

abcd is a parallelogram.
ab = 4.3, bc = 2.3, ae = 1.4, m∠adc = 116°. find the measure of cd.
enter the correct value in the box.

Explanation:

Step1: Recall properties of parallelogram

In a parallelogram, opposite sides are equal in length. So, \( AB = CD \) and \( AD = BC \).

Step2: Use given value of AB

We are given that \( AB = 4.3 \). Since \( AB = CD \) (from the property of parallelogram), we can conclude that \( CD = 4.3 \).

Answer:

\( 4.3 \)
