Question

What is the value of y in the parallelogram below? If necessary, round your answer to two decimal places.

Answer 1

@Thesmarterone

Answer 2

Rule: opposite angles of a parallelogram are congruent

so that allows us to say 4y = 104

Answer 3

And that would equal 26 so what would I do now with 3X-5?

Answer 4

Answer 5

Another rule: adjacent angles of a parallelogram add to 180 degrees (they are supplementary)

so...

(3x-5) + 104 = 180

solve for x

Answer 6

3x+99=180-99
3x=81
x=27 --- So would this be my answer?

Answer 7

yes

Answer 8

Thanks!
