Someone!

Sin is equal to opposite over hypotenuse. Can you draw the triangle with these new values?

OpenStudy (sbuck98):

No:/

OpenStudy (aveline):

We know that sine is the opposite over the hypotenuse. That means the opposite side is 5 and the hypotenuse is 13. Can you find the remaining side?

OpenStudy (aveline):

@sbuck98

OpenStudy (sbuck98):

1.666

OpenStudy (sbuck98):

@Aveline

OpenStudy (aveline):

Remember, to find the sides, we use a^2+b^2=c^2 a^2+5^2=13^2

OpenStudy (sbuck98):

wait:/ I'm lost

OpenStudy (sbuck98):

@Aveline

OpenStudy (aveline):

Ok. The hypotenuse is 13. 13 squared equals 169. We know one of the sides is 5. 5 square equals 25. We subtract: 169-25=144 12 squared equals 144. We know that the missing side is equal to 12.

I would just guess C:/

OpenStudy (sbuck98):

I was thinking C too! @Aveline

OpenStudy (anonymous):

you mean miraclemnation ? @sbuck98

OpenStudy (sbuck98):

Both of you!

OpenStudy (aveline):

It's not C

OpenStudy (anonymous):

oh

OpenStudy (aveline):

Cos x = adjacent/hypotenuse The adjacent side is 12, and the hypotenuse is 13. That means that C and D are not the answers

OpenStudy (aveline):

Do you know SOHCAHTOA?

OpenStudy (aveline):

@sbuck98

OpenStudy (sbuck98):

no

OpenStudy (anonymous):

i would say A :|) lol

It's important that you memorize this, it will be very helpful!

OpenStudy (aveline):

Tangent is opposite over adjacent. Can you figure out what the tangent is?

OpenStudy (aveline):

@sbuck98

OpenStudy (sbuck98):

13/12 @Aveline

OpenStudy (aveline):

|dw:1460572577652:dw|

OpenStudy (aveline):

13/12 would be the secant, not the tangent.

OpenStudy (sbuck98):

5/12

OpenStudy (aveline):

Correct

OpenStudy (aveline):

That means the answer is A :)

OpenStudy (anonymous):

i said A

OpenStudy (aveline):

@miraclemnation Yes, but you didn't explain your answer. Also, you said the wrong answer two times.

OpenStudy (aveline):

You said it was C. Then you said it was B (you deleted that comment). And finally, you decided it was A lol

OpenStudy (anonymous):

LOL IK cause i was guessing but if i worked the problem out it wouldve been right the first time :)
