Example 3: Given: ABCD is an isosceles trapezoid with legs AD and BC.
AC = 50
EB = x + 8
ED = 4x - 3
Find: AE, DB, and EC
Example 4: Given: ABCD is an isosceles trapezoid with upper base BC.
BE= x + 7
CE = y – 3
AE = x + 5
BD = y + 4
Find: x, y, and AC.
Example 5: Given: HGFE is an isosceles trapezoid with lower base EF.
a. Find m
b. Using what you found in part a. and given m = 43˚, find the measure of
m EHG = (6x)
m GFE = (3x)
