Question

Find the value of x in the following parallelogram

Answer 1

Explanation:

If the figure is a parallelogram then the angles opposite one another are equal

2x - 30 = x + 40 Subtract x from both sides.

2x - x - 30 = x - x + 40 Combine

x - 30 = 40 Add 30 to both sides

x - 30 + 30 = 40 + 30 Combine

x = 70
