Answer:
Step-by-step explanation: 21/25
Answer:

Step-by-step explanation:
we know that
The inscribed angle is half that of the arc it comprises.
step 1
Find the measure of the arc PQR
![109^o=\frac{1}{2}[arc\ PQR]](https://tex.z-dn.net/?f=109%5Eo%3D%5Cfrac%7B1%7D%7B2%7D%5Barc%5C%20PQR%5D)

step 2
Find the measure of arc QR

we have


substitute


step 3
Find the measure of the arc QRF
![112^o=\frac{1}{2}[arc\ QRF]](https://tex.z-dn.net/?f=112%5Eo%3D%5Cfrac%7B1%7D%7B2%7D%5Barc%5C%20QRF%5D)

step 4
Find the measure of arc RF

we have

Answer:
9
Step-by-step explanation:
Raise 3 to the power of 2.
Answer:
7.63%
Step-by-step explanation:
26000 = 18000 (x)⁵
Divide both sides by 18000
1.4444444444 = x⁵
Raise both sides to the (1/5) power
1.4444444444^(1/5) = x
1.0763169225 = x
interest = x - 1
interest = 0.0763169225
Appox interest rate = 7.63%
