Answer:
- x° = 81°
- y° = 99°
- z° = 129°
Step-by-step explanation:
I find it easiest to start with y. That way, computing x involves only one math operation instead of two.
b. y° is the sum of opposite interior angles.
y° = 48° + 51° = 99°
__
a. x° is the supplement of y°.
x° = 180° -99° = 81°
__
c. z° is the supplement of 51°. It is also the sum of the opposite interior angles.
z° = 180° -51° = 129°
z° = 48° +81° = 129°
