Trolls, dragons , and giant spiders all live in the same cave There are 2 more dragons than trolls and 3 more spiders than dragons Altogether , there are 28 creatures

(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

(-5,-28)

i graphed to on desmos.

time is equal to distance over rate so

t = d/r

need a little bit more information for the second question.
