Answer 1

Question 7: 112°

The figure is a parallelogram because there are 2 pairs of parallel sides. Since adjacent angles of a parallelogram are supplementary, the answer is 112°.

Question 8: 9

Diagonals of a parallelogram bisect each other, so

`19(2)=5x-7 \\ \\ 38=5x-7 \\ \\ 45=5x \\ \\ x=9`
