Question

The figure is a parallelogram. Solve for x.

Answer 1

Answer:

x = 7

Step-by-step explanation:

Adjacent angles of a parallelogram are supplementary.

$\therefore \: (14x + 2) \degree + 80 \degree = 180 \degree \\ \\ \therefore \: (14x + 2) \degree = 180 \degree - 80 \degree \\ \\ \therefore \: (14x + 2) \degree = 100 \degree \\ \\ 14x + 2 = 100 \\ 14x = 100 - 2 \\ \\ 14x = 98 \\ \\ x = \frac{98}{14} \\ \\ x = 7$
