Answer:
y = 126°
x = 54°
Step-by-step explanation:
y is equal to 126° because it is across from it.
All angles must add up to 360°
So, now that we know that y = 126°. . . add 126° + 126° = 252°
Subtract 252° from 360°
360° - 252° = 108°
We need to divide 108° by 2 since there are 2 sides.
108° divided by 2 = 54°
