Answer:
I think its B
Step-by-step explanation: I'm not 100% sure
We have been given a chord and tangent to a circle. We have been minor arc measure that is equal to
.
Since we know that angle formed by a secant and tangent of circle is half of the measure of intercepted arc.

We can find intercepted arc by subtracting minor arc measure from 360 degrees because minor and major arcs add up to 360 degrees.
Now we will plug given values in our formula,

Therefore, the measure of d is 121 degrees.
Answer:

Step-by-step explanation:
It must end in
(divisible by 2 rule) and the digits must sum to a multiple of 9(divisible by 9 rule).
The digit sum is
.
We want to make
as low as possible because it's a higher digit than
.
If
is as low as possible, we have that the sum is
. Uh-oh.
has to be even! So
doesn't work.
If
, we have that the sum is
. Yay!
So, the answer is 
The answer is -9 for sure
875 x 12 = 10500ft squared
950 x 6 = 5700ft squared
10500 + 5700 = 16200
the total floor area is 16200 squared feet
