Question

in parallelogram abcd if m∠cda = 110° find m∠abc.

Explanation:

Step1: Recall parallelogram angle property

Opposite angles of a parallelogram are congruent.

Step2: Match given and target angles

$\angle CDA$ and $\angle ABC$ are opposite angles in parallelogram $ABCD$.
Thus, $m\angle ABC = m\angle CDA$

Step3: Substitute the given angle value

$m\angle ABC = 110^\circ$

Answer:

$110^\circ$
