Different parallelograms require different ways of solving so theorems tell you how each parallelogram can be solved
x=−2 and y=−4
If you need explanation Just ask!
Answer:
x = -5, y= 7. You can check this yourself by plugging in the numbers.
Step-by-step explanation:
Supplementary Angles:

Arithmetically speaking, the closest 2 supplementary angles can get (in 3 and 2 digits respectively) is the upwritten.
Complementary Angles:

Simply, in this case, for angles to be numerically as close as possible - make both the angles 45°.
