Question

ABCD is a rhombus. If AD = 3y - 2 and DC = y + 8
Solve for y.

Answer 1

Solution:


A rhombus is a four-sided shape where all sides have equal length.

Then,

AD = DC

Now,

3y - 2 = y + 8

Solve for y

3y - y = 8 + 2

2y = 10

y = 5

Therefore:

3y - 2 = 3(5) - 2 = 13

y + 8 = 5 + 8 = 13

Hope this will help.
