Answer 3

this looks like trig.
there are 3 sides in a right triangle: hypotenuse (opposite the 90 deg angle)
the "opposite" side and the "adjacent" side.
for angle x which sides do we know the length of ?

Answer 4

Opposite and Hypotenuse

Answer 5

now use soh cah toa to figure out which trig function to use.
can you ?

Answer 6

Can you refresh my memory? Please?

Answer 7

the soh cah toa is supposed to "refresh your memory"

what do you think S O H is short for ?

Answer 8

I know how to get to here sine(x) = 8/17 but then i get stumped here.

Answer 9

once you get your equation
sine(x) = 8/17

you "undo" a sin by taking the inverse sin of both sides.
by definition, this gets rid of the sin on the left side:
\[ x= \sin^{-1}(8/17) \]
you need a calculator to find the answer.

they don't say if they want degrees or radians... I would guess they want degrees... so make sure your calculator is in degree mode.

Answer 10

so you divide 8 by 17 and take the inverse sin out of that?

Answer 11

yes

Answer 12

OK thank you!
Stay tuned to check on my answer :P

Answer 13

Hmm I got 61.92 So 62.00?

Answer 14

no on the degrees, and no on the rounding to the nearest 100th

Answer 15

Wait
I used cosine instead of sin sorry let me retry that.

Answer 16

Ok now i got 28.06.

Answer 17

you should get 28.07248694

to round to the nearest 100th, look at the the next number over from 07
if 5 or bigger round up. It is "2". so just keep it 07
28.07

Answer 18

Ok thank you soo much!! :)
