Answer:
34 degrees
Step-by-step explanation:
angles on a straight line add up to 180 degrees so over here the middle angle as we can see is 90 degrees so we add that to the 56 degrees. From adding them we get 146. 180 -146 is 34 degrees and that is our answer. :)

Midpoint formula
Answer:
153.86 square feet
Step-by-step explanation:
The formula for the area of a circle is : ![\pi *radius^2](https://tex.z-dn.net/?f=%5Cpi%20%2Aradius%5E2)
To work this out you would simply multiply pi by the radius of 7 squared, this gives you 153.86. This is because if you were to substitute the values into the formula you would also get the same answer.
1) Multiply pi by 7 squared.
![\pi *7^2=153.86 feet^2](https://tex.z-dn.net/?f=%5Cpi%20%2A7%5E2%3D153.86%20feet%5E2)
In this question pi is as 3.14
It's A. Sorry I can't explain.... It's obviously A
