Demarco wants to find the angle measures of this parallelogram. He knows that the first step is to find the value of x. Which of
these equations will result in the correct value of x?
A. x + 15 = 6x + 4
B. 7x − 19 + 2x − 8 = 180
C. 7x − 19 = x + 15
D. 6x + 4 + 7x − 19 = 180
A. x + 15 = 6x + 4
B. 7x − 19 + 2x − 8 = 180
C. 7x − 19 = x + 15
D. 6x + 4 + 7x − 19 = 180

Step-by-step explanation:
When finding flooring needed we are finding for area. We know the formula for finding the area of a circle is A= so we plug in our known variables...
we know r because radius is half of diameter and diameter was given in problem. So half of 18 is 9.
r=9
A=
A=81
A=254.469
