What is this one i cant seem to figure it out
pshichka [43]

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

Ana is having dinner at a restaurant. Her bill before adding sales tax and tips is $23.20. The restaurant add the sales tax of 7
Aneli [31]
Start by finding 7% of the $23.20:

\frac{7}{100} *23.20=1.624

Now add this to $23.20:

23.20+1.624=24.824

Now, let's find 18% of this new total with tax to find the tip amount:

\frac{18}{100} *24.824=4.46832

This is the tip amount. And finally, let's add this to the 24.824:

24.824+4.46832=29.29232

Not sure if you were given any instructions about rounding, but Ana's cost will be around $29.29.

Hope this helps.
