Solution to QOTD 3/24/2020

x = 70*, y = 110*

The instructions tell you that the image is a parallelogram, which is quite important! Here are a few rules to remember when it comes to parallelograms:

a) Opposite angles are congruent.

b) Consecutive angles are supplementary.

Therefore given that angle D is 70*, angle B must be 70* also. And then, using rule (b) from above, 180 – 70 = 110.
