We know, a number is divisible by 9 if the sum of digits is also divisible by 9.
Also, since A is an digit, so A is in between 0 to 9.
2+A+5+A+0+A+2 = 3A + 9
3A + 9 should be divisible by 9.
3A + 9 = 9n
A = (9n -9)/3
For n= 1 :
A = 0
For n=2 :
A = 3
For n= 3 :
A = 9
After this A > 9 which is not accepted.
Therefore, the digit A can be 0, 3 and 9 .
Hence, this is the required solution.
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°

You'd make a total of $25,125.46 and the interest is $11,125.46
Y = 3.75x...he built 5 desks...so x = 5
y = 3.75(5)
y = 18.75 hrs
