Answer:

Explanation:

In a a parallelogram, opposite sides are equal.

6x = 24

Divide both sides by 6


(6x)/(6)=(24)/(6)

x = 4

In a parallelogram, opposite angles are equal.

∠B = 76°

In a parallelogram, adjacent angles are supplementary.

∠A + ∠D = 180°

∠A + 76 = 180

∠A= 180 - 76

∠A = 104°

∠BAC + ∠CAD = ∠A

∠BAC + 21 = 104

∠BAC = 104 - 21

∠BAC = 83°
