Question

Heyy PARTY PEOPLE!! Help me, and u can get a fan or a medal!!

9.
Find the value of x. Round to the nearest tenth. The diagram is not drawn to scale.

triangle with sides X, 11 and a 24 degree angle (2 points)

Answer 1

what do you know about trig functions?

Answer 2

I need a walkthough

Answer 3

sine cosine and tangent

Answer 4

which trig function uses the next.to (adjacent) and hypotenuse

Answer 5

tangent never looks at the hypotenuse; tan = over/nextto

whats you next best one?

Answer 6

might help to write out the functions :) just as a review

Answer 7

Cosine

Answer 8

cosine is the winner !!

now, cosine = next.to/ hypotenuse

Answer 9

with what is given that leaves us:

cos(24) = 11/x

can you solve for x?

Answer 10

manually?? or can i use a calculator?

Answer 11

youll need a calculator or table to determine cos(24)

but just the setup would be useful. How would we move this equation around to solve for x?

Answer 12

I have NO CLUE, but the calculator is telling me 12.04

Answer 13

cos(24) = 11/x

x = 11/cos(24)

and yes, abt 12.04 is what i get as well

Answer 14

Oh ok thanks I understand now, and I have another question if you don't mind

Answer 15

if its a quick one, I have real job stuff that i have to attend to :)

Answer 16

kk hold on

Answer 17

What is the value of w to the nearest degree?

Diagram (1 point)

25°
35°
40°
45°

Answer 18

the idea is to find v in order to find w, right?

Answer 19

If this isn't quick you don't have to help, I don't want to waste your time

Answer 20

but yes

Answer 21

itll be quick enough, go ahead and write out the sin cos tan function for me so we can reference them

Answer 22

sin = Opposite/Hyp.
cos = adjacent/ Hyp.
tan= opposite/adjacent

Answer 23

lets name the parts to compare as well

Answer 24

in my mind, over is the same as opposite :)

Answer 25

oh ok,

Answer 26

so, would you agree that the sine function works best for us on this one?

Answer 27

Yes
