Find the measure of /x for which wxyz is a parallelogram.

3t - 15 = 2t + 10

t = 25

<Y = 2(25) + 10 = 60

<X = 4r  

4r + 60 = 180

4r = 120 (<X = 4r)

<X = 120

Hope this helps, have a BLESSED and wonderful day, as well as a safe one! Also, have a merry Christmas!  

i used to know how to do this in 7th but i forget easily

step-by-step explanation:

use this formula:

p(a\b) = p(a and b)/p(b).

take it from here.
