Answer:
????
Step-by-step explanation:
number 1 could be 2 different answers
2x+y=8 is the equation perpendicular to x-2y=8.
If AB and CD are parallel lines and PR is the transversal, then angle PRD = angle APR by alternate interior angle theorem.
Angle PRD = 120 degrees so, 65 + x = 120 degrees
120 - 65 = 55 degrees
