2/4 is shorter distance. I think. Hope its helps !!!!!!!

is the only acute angle whose sin = 1/2. Therefore, cos (

) =
X is left and right
hmm
see the aproximate slope
see endpoints
ok, so from about (0,3) to (35,30)
slpoe is 27/35
so
y=(27/35)x+3 about
so when x=
ok, so according to the garph, when x=35, y=30, not 20
ok, so when x=40
y=(27/35)x+3
y=(27/35)*40+3
y=33.8571 about for x=40
In the first one the options they give you are wrong, in fact you can prove it yourself, none of the options will give you as a result 10
I hope I helped you out
greetings!
