There is no way that is correct @Bookworm14
OpenStudy (anonymous):
how do u know i am in

The hypotenuse CANNOT BE SMALLER than a leg
OpenStudy (bookworm14):
the triangle is not drawn to scale so it will look wrong

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

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

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!!

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 :)
OpenStudy (bookworm14):
ok, thank you!
