Check the picture below.
let's firstly convert the mixed fractions to improper fractions.

Answer:
0, -1
Step-by-step explanation:
This question was answered in another place since you asked it twice. Please refer to the other place that you asked the same question.
To figure out the degrees, you would create a ratio.
Since there are 360 degrees in your circle, that would be representative to 100 (because both are the total of what you want to find), and x would be representative to what degrees 65 is equal to.
your ratio should look like,
65/100=x/360
cross multiply and get
65(360)=100x
23400=100x
x=234
It looks hard to read like this, but if you write it out on your paper it should make more sense!
To cover at least 170.5 sq.ft. the width must be at least 11 feet
W=170.5sq.ft / 15.5 ft = 11ft
