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:
proper fractions
Step-by-step explanation:
Proper fractions have a numerator that is always less than the denominator. In arithmetic, using positive numbers, proper fractions represent the numbers between 0 and 1. , , and are all proper fractions. Improper fractions have a numerator that is greater than the denominator.
