Question

find the value of x.Round to the nearest tenth.

Answer 1

x is the height the hypotenuse side is 14 and the angle is 33degrees

Answer 2

shadow u there

Answer 3

Depending on whether the x is adjacent or opposite of the angle, use either sin or cos. You can set it up something like this:

\[\sin 33 = \frac{x}{14}\]

And solve for x. Make sure that you use sin or cos, whichever one is appropriate, though.

Answer 4

so how do i write that on the ti 30x calculator

Answer 5

x is oposite to 33degrees and hypothenuse is 14

Answer 6

So which is appropriate, sin or cos? Which ratio involves both the opposite and the adjacent?

Answer 7

so i need sine

Answer 8

sin

Answer 9

Right.

Answer 10

So how do you solve the above equation for x?

Answer 11

i guess i press sin then put 33 divided by 14

Answer 12

do i press sin then (33 / 14)

Answer 13

or 33sin(14)

Answer 14

Not divided by 14.

Answer 15

Multiply. But yes, sin then 33 then times 14 would do it, and 14 then times then sin 33 should also work.

Answer 16

i got 7.98

Answer 17

Hm. Should be 13.998 or so.

Answer 18

i get .9 or 7.6 or .007 can u show me a formula on how u did it

Answer 19

14 * sin(33). It's the only solution to the equation above.

Answer 20

i got the same thing 7.62494649

Answer 21

Simpler calculators may require you to do:

33
<sin button>
<x button>
14
<=>

Answer 22

i got the texas instrument TI-30XTIS

Answer 23

i just got 7.983422555

Answer 24

And I have no idea how it works :) I'm just guessing.

Answer 25

so u dont know how to do it?

Answer 26

On your calculator? No idea.

Answer 27

it cant be 13.998

Answer 28

since hypotenuse is 14

Answer 29

I'm an idiot, I'm sorry.

Answer 30

shadow can u put the sine cosine tangent formulas again see if im right

Answer 31

7.6 was correct. I've been using degrees where things expected radians.

Answer 32

ur not an idiot mistakes are always made that is what makes us humans

Answer 33

is it 33 sin(14) or 14 sin (33)

Answer 34

It's 14 sin(33)

Answer 35

in a cosine let say its the same numbers how u find the end result
