What is the measure of angle Z?

Step-by-step explanation:

The given quadrilateral is an isosceles trapezoid. This is because the two bases(lower and upper) are equal. The lower base angles are congruent. The upper base angles are also congruent. Therefore, each lower base angle is supplementary to the upper base angle on the same side. This means that

Angle W and angle Z are Supplementary. The sum of supplementary angles is 180°. It means that

112 + angle Z = 180

Angle Z = 180 - 112 = 68 degrees

answer: the answer is 35%

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

4. multiply that answer by 100 and add the % symbol to express the answer as a percentage.

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.

2. divide the increase by the original number and multiply the answer by 100. if your answer is a negative number then this is a percentage decrease.

hope this : )
