31. In parallelogram ABCD below, the measure of ∠BCD is 98° and the measure of ∠CDB is 38°. What is the measure of ∠BDA ?

Answer and Explanation

Your Answer is

Correct Answer is C

Explanation

The interior angles between parallel lines are equal, so ∠BDA=∠CBD; and the sum of the interior angles of the triangle is 180˚, so ∠CBD=180°-∠BCD-∠BDC=180°-98°-38°=44° So choose C.
