I will use this notation m arc AB to name the measure of the arc AC in degress, going from A to B counterclock wise.
Also, note that the measure of an arc is equal to the measure of the central angle from which the arc is generated.
With that:
1) m arc AB
m arc AB is equal to the angle AOC
The angle AOC is indicated to be 49°, so m arc AB is also 49°.
Answser: 49°
2) m arc ABC
m arc ABC is equal to 360° - angle COA = 360° - 107° = 253°
3) m arc BAC
m arc BAC is equal to angle AOB + angle COA
m arc BAC = 49° + 107° = 156°
Answer: 156°
4) m arc ACB
m arc ACB = 360 ° - angle AOB = 360° - 49° = 311°
Answer: 311°

Answer:
The equation of circle is 
(D) is correct option.
Step-by-step explanation:
Given that,
Points (6,5), (7,2), (9,6) and (10,3) are vertices of an inscribed square.
We need to calculate the distance between (7,2) and (9,6)
Using formula of distance
Put the value into the formula
The radius will be
We need to calculate the center of the point (7,2) and (9,6)
Using formula of center point
For x axis,
Put the value into the formula
For y axis,
Put the value into the formula
We need to find the equation for the circle
Using formula of equation of circle
Put the value into the formula
Hence, The equation of circle is
(D) is correct option.
Cause two of the sides will be the same(the shortest ones)
The others will also be the same (the longest ones)
the original patio was 12 x 12 ,
if you take 5 feet off the height that would make new height 12-5 = 7 feet
and add 5 feet to the length 12 +5 = 17 feet
so new patio would be 7 x 17
7 x 17 = 119 square feet
so A would be the correct answer
