To find: The value of x and measure of all
Answer to Problem 11WE
The values of angles A , B , C and D are 40, 140, 140 and 40 respectively. Value of x is 10.
Explanation of Solution
Given:
Consider the trapezoid as shown below:
The congruent angles A and D are
Calculation:
For the isosceles trapezoid,
Hence,
Angle A and D is calculated as follows:
Sum of one sided interior angles must be 180.
Hence,
And,
Thus, the values of angles A , B , C and D are 40, 140, 140 and 40 respectively.
