Question

.

Answer 1

do you have a link or the actual question you can post?

Answer 2

The opposite side of the triangle is the side that is across from the angle observed.

Answer 3

First thing, can you tell me the trig ratios required for this question?

Answer 4

Hint: SOH CAH TOA

Answer 5

Perfect, so here what side do you have?

Answer 6

Correct :)! Alright so we have the angle and the adjacent side, and you already know we're looking for the opposite side, so first what ratio from the ones you gave would you use?

Answer 7

*hint SOH CAH TOA

Answer 8

That's alright, as you see we have adjacent, so you know we have to use that, and we're looking for the opposite, which ratios mentions both adjacent, and opposite?

Answer 9

sine oposite hypotenuse cosine adjacent hypotenuse tangent oposite adjacent

Answer 10

SOH CAH TOA

Answer 11

Right! Are you sure you're not a professor in mathematics? Haha, anyways so lets continue you can set it up as so,

\[\tan \theta = \frac{ opp }{ adj } \implies \tan 46.63 =\frac{ opp }{ 71 }\]

Answer 12

Do you see how I achieved that @jamielovesmickey

Answer 13

To find the opposite, you need to plug it into an equation. You have the adjacent of the angle, so use a method that uses the adjacent and opposite. This would be tangent. The tangent of the angle is the opposite divided by the adjacent. You'll have to use a calculator for this though. Your equation is O/71=tan(46.63). Use a calculator and find the tangent of 46.63, and then multiply it by 71 to get the opposite.

Answer 14

You can punch that into a calculator, but we are looking for the opposite side, so lets do some algebra, what would you do to find opp? (Isolate the opposite side, meaning get it on it's own).

Answer 15

Correct, now just do that, and boom you have the opposite side :)!

Answer 16

\[(\tan46.63)(71) = opp\]

Answer 17

Can you tell me what you got as your final answer, so I can confirm it.

Answer 18

this was a nice review for me as well :) I have finals coming up soon and I only learned about this like a month ago, thanks from me as well :)

Answer 19

Np :)

Answer 20

Use it in degrees, I see you used radians for this. Remember we have the degree 46.63 so that should give you a hint ;)

Answer 21

or use this http://web2.0calc.com/

Answer 22

it's an online scientific calculator

Answer 23

that is correct :D

Answer 24

Yup that's right, you can use up to 2 significant digits, since that's the smallest amount of digits in your question, meaning 75.

Answer 25

75 as your final answer

Answer 26
