A.
2 1/2 * 3
5/2 * 3 = 15/2 = 7 1/2 ft used
B
8 - 7 1/2 = 1/2 feet left.
Answer:
2.33
Step-by-step explanation:
If you put the numbers into the radius formula you should end up with this number hope this helps:)
<span>3.4 - 2.8d + 2.8d - 1.3 = </span>3.4 - 1.3 - 2.8d + 2.8d = 3.4 <span>- 1.3 = 2,1

we are given that
angle(ACF)=90
angle(ACB)=61
sum of all angles along any line is 180
so, we get
angle(ACF)+angle(ACD)=180
we can plug value
90+angle(ACD)=180
angle(ACD)=90
now, we can use formula
angle(ACD)=angle(ACB)+angle(BCD)
now, we can plug values
and we get
90=61+angle(BCD)
90-61=61-61+angle(BCD)
angle(BCD)=29................Answer
