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
y=|x-5.5| is trans 5 units right

Step-by-step explanation:
I JUST KNOW
Critics of the Catholic Church were able to quickly replace any writings the church destroyed.
If two lines are perpendicular to each other, the product of their slope is -1.
so,... .hmmm let's check the slope of each one, and their product then.
