Question

PLEASE HELP QUICKLY

Answer 1

@Vocaloid

Answer 2

you are given sin(theta) = w/l and asked to find theta

therefore you just need to take the arcsin of both sides

theta = arcsin(w/l)

and plug in your w and l values

Answer 3

be sure your calculator is in degrees mode

Answer 4

sorry idk

Answer 5

the problem states that width = 4.33 and l = 5.0

therefore you simply need to calculate arcsin(4.33/5.0)

Answer 6

90

Answer 7

hm. I don't think it's 90

depending on what type of calculator you're using there should be a sin^-1 button

Answer 8

I get something a little closer to ~60 degrees

Answer 9

oh

Answer 10

ok ill go with 60, and yea i just used a normal caluculater
