Please help!!!<br><br> What is the measure of ∠DCB?<br> Enter answer below<br> __
Tom [10]

Answer:

m<DCB = 84°

Step-by-step explanation:

ABCD is a parallelogram since it has two sets of parallel sides.

Opposite angles in a parallelogram are congruent.

Consecutive angles in a parallelogram are supplementary.

<DCB is consecutive to <D.

m<DCB + m<D = 180°

m<DCB + 96° = 180°

m<DCB = 84°
