Answer:
x = 129°
y = 82°
Step-by-step explanation:
x is supplementary to the angle corresponding to 51°, so is supplementary to 51°.
x = 180° -51° = 129°
__
y is an alternate exterior angle to the unmarked angle between 47° and 51°, hence congruent to that angle. Its measure is ...
y = 180° -47° -51° = 82°
