Final answer:
To find the measure of angle ZE in an isosceles trapezoid, we subtract the measures of the congruent base angles from 180 degrees.
Step-by-step explanation:
To find the measure of angle ZE in the isosceles trapezoid DEFG, we need to use the properties of isosceles trapezoids.
In an isosceles trapezoid, the base angles are congruent. So, angle D = angle E and angle F = angle G.
Since the sum of the angles in a quadrilateral is 360 degrees, we can find the measure of angle ZE by subtracting the measures of angles D and F from 180 degrees. Therefore, angle ZE = 180 - angle D - angle F.
Based on the information given, we can see that angle D is 62 degrees (option B) and angle F is 18.4 degrees.
Therefore, angle ZE = 180 - 62 - 18.4 = 99.6 degrees.
So, the measure of angle ZE in the isosceles trapezoid DEFG is 99.6 degrees.
