Answer:
73
Step-by-step explanation:
Since DA is the diameter, this means that you can divide the circle into two half-circles. You will solve with the right half-circle. A half-circle has a 180 total degrees. Add up the values given and solve for x.
(2x) + (7x - 4) + (85) = 180
2x + 7x - 4 + 85 = 180
9x - 4 + 85 = 180
9x + 81 = 180
9x = 99
x = 11
Now that you have the value of x, solve for m∠CZB.
m∠CZB = 7x - 4
m∠CZB = 7(11) - 4
m∠CZB = 77 - 4
m∠CZB = 73
Answer:
9.25 per hour.
Step-by-step explanation:
In order to determine the hourly pay rate of Craig, you must divide the money earned by the hours worked. In this case, divide 37/4 and 64.75/7. For each equation, your answer should be 9.25. Therefore, that is Craig's hourly pay rate.
Answer:
Area = 40
Step-by-step explanation:
The area of a rhombus is
Area = a*b/2
Where a and b are the lengths of the diagonals.
Area = 8 * 10/2
Area = 40
