Question

the movement of the progress bar may be uneven because questions can be worth more or less (including zero) depending on your answer. find the measure of ∠d, and the perimeter and area of parallelogram abcd. 17 cm 8 cm 28° 20 cm ∠d = 152°, p = 74 centimeters, a = 160 square centimeters ∠d = 62°, p = 37 centimeters, a = 160 square centimeters ∠d = 162°, p = 74 centimeters, a = 340 square centimeters ∠d = 62°, p = 37 centimeters, a = 340 square centimeters

Explanation:

Step1: Find ∠D

Adjacent angles in parallelogram are supplementary. ∠A = 28°, so ∠D=180 - 28=152°.

Step2: Calculate perimeter

Opposite sides of parallelogram are equal. P = 2(17 + 20)=74 cm.

Step3: Calculate area

A = base×height = 20×8 = 160 cm².

Answer:

∠D = 152°, P = 74 centimeters, A = 160 square centimeters
