HELP PLS For what values of the variables must ABCD be a parallelogram? Show work in full for brainliest.

x=42°

y=48°

Step-by-step explanation:

For this to be a parallelogram m∠A = m∠C and m∠B = m∠D.

y+48=2y

subtract y from both sides

y=48

2x=3x-42

Subtract 3x from both sides

-x=-42

divide both sides by -1

x=42

so the rectangle is 80cm (area)

now to find the area of a triangle.

base times height.

4 times 8.

your answer is 96cm.

hope this .
