Given a circle with a radius of 2, which is the degree measure of an arc whose length is 1/2 pi? a. 30 degrees b. 45 degrees c. 60 degrees d. 76 degrees

(sin 42)/31. = sinx)/37

sinx = 37 (sin42)/31

= 37× 0.66/31 = 0.787

x= 51.9

other angle opposite to y = 180-51.9-42

= 180- 93.9 =86.1

so

sin42)/31 = sin 86.1)/y

0.021 = 0.997 /y

y= 0.997/0.021 =47.47

7

step-by-step explanation:

i'm assuming you need to figure out how many campers go into each tent.

i got the answer by:

24+4=28

28/4=7  

-7/8

step-by-step explanation:

instead of subtracting you add the -6/8 and -1/8
