What is the measure of BFC,​

Mathematics
1 answer:
Y_Kistochka [10]3 years ago
7 0

Answer:

108

Step-by-step explanation:

Since angle AFB and angle BFC are next to each other and form a straight line, we can subtract 72 from 180 to get the missing angle measurement. (all straight lines add up to 180)

180-72=108

So 108 would be your answer

A round swimming pool has a circumference of 66 feet. Carlos wants to buy a rope to put across the diameter of the pool. The rop
beks73 [17]
We can find the diameter of the circle by replacing some values in the formula for circumference. The formula for find the circumference is pi * d, where pi could equal 3.14 or 22/7 and d is the diameter. After dividing pi from both sides (I used 3.14), we have the total of about 21.01, which would be our diameter. We add 4 more feet into it, resulting in 25.01 feet, and we just multiply that by $0.45 to get the total price.

We get around $11.25 as our total price.
