Question

i need some answers checked

Answer 1

i chose 45

Answer 2

@Vocaloid

Answer 3

"distance the person will walk on the ramp" so they are asking about the hypotenuse

so you have the hypotenuse and the adjacent side, which trig ratio is this?

Answer 4

sine and cosine?

Answer 5

it can't be both

which trig ratio involves the adjacent and hypotenuse?

Answer 6

cosine

Answer 7

cosine

Answer 8

good

now calculate the hypotenuse of the triangle

Answer 9

i think somewhere near 55-60 feet?

Answer 10

cos(theta) = adjacent/hypotenuse

cos(27 degrees) = 50/hypotenuse

solve for hypotenuse

Answer 11

try to cross multiply first and solve for the hypotenuse

Answer 12

i got somewhere near 56, i think i did it wrong..

Answer 13

56 is the correct sol'n

Answer 14

i chose C

Answer 15

not quite

remember that cos is adjacent/hypotenuse not opposite/hypotenuse

Answer 16

oh, B then,

Answer 17

which side is adjacent to angle x?

Answer 18

which side of the triangle is next to angle x? without being the hypotenuse?

Answer 19

there are two sides that aren't the hypotenuse. the 18 side and the 80 side. which one is closer to angle x?

Answer 20

sorry, pc reset, i'm back

Answer 21

18?

Answer 22

@Vocaloid

Answer 23

Good

So 18 is the adjacent side

Making cos = adjacent/hypotenuse =?

Answer 24

0.219?

Answer 25

@Vocaloid sorry i had to do some errands

Answer 26

Good but it rounds to .220 = your solution
