what is the question

anonymous · Answer

oh srry have no idea

@Xnlovely, could you help?

solomonzelman · Answer

opposite/hypotenuse

anonymous · Answer

im not 100% sure but i got 67.38013505195957 for that angle on  Question 1

solomonzelman · Answer

I doubt that

solomonzelman · Answer

what is the opposite side (when looking from angle x) ?
what is the hypotenuse of the triangle?

znappydooz · Answer

Could you guideme through the process?

solomonzelman · Answer

please label the opposite side and the hypotenuse of the triangle as I asked.

anonymous · Answer

what do you think then i honestly did not know how to do this i gave it my best guess

solomonzelman · Answer

Znappy, any feedback you can give me?

what is (or how long is) the hypotenuse?
what is (or how long is) the opposite side?

znappydooz · Answer

the hypotenuse is 13 cm long

solomonzelman · Answer

yes, correct, and the opposite side ?

solomonzelman · Answer

(opposite side, - opposite to angle x)

znappydooz · Answer

12 cm?

solomonzelman · Answer

yes

solomonzelman · Answer

so, sin(x) = opposite / hypotenuse

and as we have just now found out,   sin(x) = 12 / 13

znappydooz · Answer

That equals 0.92

solomonzelman · Answer

yes, something about that, I don't have a calc with me right now.
for your next part,

do you know what complementary (they misspelled it) angles are?

znappydooz · Answer

Not so sure :P

znappydooz · Answer

Are we still in the first question?

solomonzelman · Answer

no, on the second one.
going slowly into it, kinda

solomonzelman · Answer

complementary angles are angles that add to 90. (simply speaking)

such that angles A and B are complementary is    A+B=90

solomonzelman · Answer

Also, do you know that the sum of all angles in a triangle  (regardless of what triangle you are dealing with) is 180 degrees ?

znappydooz · Answer

Yes, so would I have to substract 92 - 90 and it will give me the angle of angle x?

solomonzelman · Answer

no no...

solomonzelman · Answer

you need to determine the relationship as given in part 2

solomonzelman · Answer

When you look from angle x,

label for me the

- adjacent side
- opposite side
- hypotenuse

znappydooz · Answer

Adjacent = 5 cm
opposite = 12 cm
hypotenuse = 13 cm

solomonzelman · Answer

Yes, those are correct!
Now, in the picture I re-drew from the attachment, but I labeled the other angle as y for convenience. |dw:1429547653672:dw|
