(1) Find the values of x and y for the isosceles trapezoid below.
(2) If angle BAD is 35 degrees, what is the measure of angle FED and angle ADC?
+129907 1) Assuming that EF is the midline
sum of base lengths / 2 = midline length
(10 + 8x - 43) / 2 = 2x mult through by 2
10 + 8x - 43 = 4x
-33 + 8x = 4x
-33 = -4x
x = 33/4
And
6y -1 = 2y + 3
6y - 2y = 3 + 1
4y = 4
y = 1
2) FED = BAD = 35°
ADC is supplemental to BAD = 180 - 35 = 145°
