For what values of x and y must each figure be a parallelogram?
Need help please, and explanation.

Answer 1

y = 30

x = 60

Explanation:

4y and 2y are consecutive angles, which means they are equal to 180° when added together

that is the same with x and (5x - 180)

to solve, you set the equations to 180

solving:

4y + 2y = 180

6y = 180

y = 30

x + 5x - 180 = 180

6x = 360

x = 60
