Answer:
103
Step-by-step explanation:
angles formed on the same line of a parallelogram are supplementary angles
( the angle with the measure of 77 degrees and the angle labeled "x" are formed on the same line which means they are supplementary )
supplementary angles add up to equal 180
hence, 77 + x = 180
180 - 77 = 103
Hence, x = 103
Answer: 2xy
Step-by-step explanation:
