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

shadow u there

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.

so how do i write that on the ti 30x calculator
anonymous
  • anonymous
x is oposite to 33degrees and hypothenuse is 14
shadowfiend
  • shadowfiend
So which is appropriate, sin or cos? Which ratio involves both the opposite and the adjacent?
anonymous
  • anonymous
so i need sine
anonymous
  • anonymous
sin
shadowfiend
  • shadowfiend
Right.
shadowfiend
  • shadowfiend
So how do you solve the above equation for x?
anonymous
  • anonymous
i guess i press sin then put 33 divided by 14
anonymous
  • anonymous
do i press sin then (33 / 14)
anonymous
  • anonymous
or 33sin(14)
shadowfiend
  • shadowfiend
Not divided by 14.
shadowfiend
  • shadowfiend
Multiply. But yes, sin then 33 then times 14 would do it, and 14 then times then sin 33 should also work.

i got 7.98
shadowfiend
  • shadowfiend
Hm. Should be 13.998 or so.
anonymous
  • anonymous
i get .9 or 7.6 or .007 can u show me a formula on how u did it
shadowfiend
  • shadowfiend
14 * sin(33). It's the only solution to the equation above.

i got the same thing 7.62494649

Simpler calculators may require you to do: 33 14 <=>

i just got 7.983422555
shadowfiend
  • shadowfiend
And I have no idea how it works :) I'm just guessing.
anonymous
  • anonymous
so u dont know how to do it?
shadowfiend
  • shadowfiend
On your calculator? No idea.
anonymous
  • anonymous
it cant be 13.998
anonymous
  • anonymous
since hypotenuse is 14
shadowfiend
  • shadowfiend
I'm an idiot, I'm sorry.
anonymous
  • anonymous
shadow can u put the sine cosine tangent formulas again see if im right
shadowfiend
  • shadowfiend
7.6 was correct. I've been using degrees where things expected radians.
anonymous
  • anonymous
ur not an idiot mistakes are always made that is what makes us humans
anonymous
  • anonymous
is it 33 sin(14) or 14 sin (33)
shadowfiend
  • shadowfiend
It's 14 sin(33)
anonymous
  • anonymous
in a cosine let say its the same numbers how u find the end result
