Answer:
The angle of rotation is 214°.
Step-by-step explanation:
Formula for arc length:
The length of arc is the product of radius and the central angle ( in radian).
L= rθ
L= Length of arc
r= Radius
θ= Central angle (in radian).
Here L= 280 feet and diameter =150 feet.
Radius feet =75 feet
radian.
We know that,
π radian= 180°
= 214°
5 is a factor
45s–35
45s = 5*9*s
35 = 5*7
45s–35 = 5(9s-7)
Answer: 2/4 simplified to 1/2
314
