Answer:
121 degrees
Step-by-step explanation:
The "arc length" formula is s = rФ, where Ф represents the central angle in radians (not degrees).
Here r = 18 ft and s = 38 ft, and so:
38 ft
s = rФ becomes Ф = ------------ = 2.111 radians
18 ft
which, in degrees, is:
2.111 rad 180 deg
------------- * --------------- = 121 degrees, to the nearest degree

Answer:
2/3
Step-by-step explanation:
2 / (1/a + 1/b)
2 / (1/1 + 1/(½))
2 / (1 + 2)
2/3
-sqa(3.24-sqa(1.44+sqa(12.25)))
= -sqa(3.24-sqa(4.94)) (since sqa(1.44+sqa(12.25))=sqa(4.94))
=-sqa(3.24-2.22261)
= - sqa(1.01739)
= - 1.00866
10 N is correct give m brainlist pleaseeee !:)
