I got A is that correct? (will post pic below)

OpenStudy (anonymous):

yes it is

OpenStudy (bookworm14):

@sameri I am just now posting the question ?>???

OpenStudy (anonymous):

oh i was talking to another person but it is correct

OpenStudy (bookworm14):

ok thank you! :)

OpenStudy (anonymous):

np any time

OpenStudy (anonymous):

There is no way that is correct @Bookworm14

OpenStudy (anonymous):

how do u know i am in

OpenStudy (anonymous):

10 grade

OpenStudy (anonymous):

The hypotenuse CANNOT BE SMALLER than a leg

OpenStudy (bookworm14):

the triangle is not drawn to scale so it will look wrong

OpenStudy (bookworm14):

it says right in the image *not drawn to scale*

OpenStudy (anonymous):

see she gets it

OpenStudy (anonymous):

Scale doesn't matter. The hypotenuse as a concept cannot be smaller than a leg

OpenStudy (bookworm14):

I know, but that is what the math came out to??

OpenStudy (anonymous):

no the hypotenuse does matter i give you that but i know math

@Agl202 @ganeshie8 @Kainui @AravindG

OpenStudy (aravindg):

@LegendarySadist is right. Hypotenuse is always larger than other two sides. Let's try to do this together. What does sin 35 give you in this figure?

OpenStudy (bookworm14):

0.6 (rounded)

OpenStudy (aravindg):

I mean take opp side/hypotenuse in figure.

OpenStudy (bookworm14):

16/x

OpenStudy (aravindg):

Good so 0.6=16/x Can you solve for x now?

OpenStudy (bookworm14):

0.6x = 16 16 / 0.6 = 26.7

OpenStudy (aravindg):

Well done.

OpenStudy (bookworm14):

but that is not an answer choice?

OpenStudy (aravindg):

Remember. You approximated before you got the final answer!!

OpenStudy (aravindg):

Try plugging in real value of sin 35 instead of 0.6

OpenStudy (bookworm14):

27.9 ? but here is how i am being taught, just so you knw where my mind is on this sin = opp/hyp opp * sin (angle) = hyp 16 * sin (35) = 9.2

OpenStudy (aravindg):

SEE THIS: a=b/c ac=b NOW THIS: sin = opp/hyp sin *hyp=opp

OpenStudy (aravindg):

27.9 looks good :)

ok, thank you!
