Question

A quadrilateral with 90 degree angles is shown. The lengths of the left and right sides are 10 and 2 y + 4. The lengths of the top and bottom sides are 18 and 10 + 2 x. What is the value of y? 3 4 5 6

Answer 1

A. 3

Explanation:

Answer 2

The left and right sides would be the same length.

Set the two sides equal and solve for y:

10 = 2y +4

Subtract 4 from both sides:

6 = 2y

Divide both sides by 2:

y = 6/2

y = 3
