Calculate x and y, with an adequate explanation. for points.

Opposite angles of a parallelogram are congruent.
Adjacent angles of a parallelogram are supplementary.

Set the measures of the two opposite angles equal and solve for x.

5x - 20 = 2x + 43

3x = 63

x = 21

Set the sum of two adjacent angles equal to 180.

5x - 20 + 4y - 5x = 180

-20 + 4y = 180

4y = 200

y = 50

A)26•2=52there are 2 sides with the same length116-52=64the other 2 side have to be half of 64 each64/2=32the width is 32b)make two sentences about these steps because your teacher knows how you write and explain things.

If there are four friends then each would get, 1.25 or 1 1/4. so this is how i solved 5 ÷ 4 = 1.25 . hope this ; )
