Answer:
x = 53°
y = 106°
Explanation:
In a trapezoid the adjacent angles are supplementary. This means that they add up to 180.
a- Finding the value of x:
Angle A and angle B are supplement angles. This means that:
angle A + angle B = 180
x + 127 = 180
x = 180 - 127
x = 53°
b- Finding the value of y:
Angle C and angle D are supplement angles. This means that:
angle C + angle D = 180
y + 74 = 180
y = 180 - 74
y = 106°
Hope this helps :)
