Question

Find angles X and Y for the question

Answer 1

9514 1404 393

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°

Answer 2

Answer:

x = 129

y = 82

Step-by-step explanation:

x + 51 = 180

x = 180 - 51

x = 129

y + 51 + 47 = 180

y = 98 - 180

y = 82
