PLA ANSWER I DONT KNOW THIS

x=45

Step-by-step explanation:

I can give you two solutions

First solution:

In we know that

same case for in

so we have that

we leave it like that because it's convenient

Now by properties of parallelograms we know that opposite sides add up to 180

so one angle is 45  and the other one is 135

Solution 2

if we look at DEBF we can say that it's a cyclic quadrilateral

because opposite sides add up to 180

in our case

so for the other to angles is also true

so that's the measure of one angle of the parallelogram

the other angle x is

There you go choose yourself
