As AB is a diameter, then m∠CBA=180^{0}-75^{0}=105^{0}.
∠CBA is a central angle, so its measure multiplied by radius is the length of arc AC.
Note that

and

. Then

and length of the arc is

.The correct answer is 22 in.
Answer:
I am not sure what you mean by simplifying to a single power of 3 but 3^6 x 3 would be the power 3 over 7 = 3^7
a. The construct the expression for the area of the rectangle in terms of x is y=2.5x
b. The area should be 2,560.
Given that,
- the length of a rectangular house is two and a half times its width.
Based on the above information, the calculation is as follows:
a) The expression should be y = 2.5x
b) The area should be
= 2560
