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)
