Question

What is the value of y in the parallelogram below?

65⁰
/5yº
A. 13
B. 60
C. 110
D. 23
K

Answer 1

Answer: D, 25

Explanation:

A parallelogram is 360 degrees, and every angle appears twice, so we can set up an equation to solve for the missing variable.

`360 = 2(65) + 2(5y)`

Multiplying each angle by two shows that each angle appears twice in the shape, and once we multiply the values, we can simplify the equation to:

`360-130=10y`

360 - 130 is 230, so divide both sides by 10 and you get 23 as the answer.
