alright tan theta = what ? in general like cos = adjacent /hyp
anonymous
  • anonymous
tan=o/a
Nnesha
  • Nnesha
right opposite over adjacent |dw:1443993344258:dw| but c is the hypotenuse LONGEST side of right triangle don't use 90 degree angle to find any side

I also tried using sin33=a/10, but I didn't know what sin33 =
Nnesha
  • Nnesha
|dw:1443993462650:dw| so yes that's right
Nnesha
  • Nnesha
use calculator for sin (33)
Nnesha
  • Nnesha
but i guess you don't have to solve for isn't it like the previous question we should include sin /cos /tan ration in asnwer
anonymous
  • anonymous
I believe so, because I tried to put in sin 33 in the calculator but the answer came out wrong
Nnesha
  • Nnesha
hmm what do you mean wrong ?
Nnesha
  • Nnesha
what did you get ?
anonymous
  • anonymous
so I multiplied 10*sin33 inputted that into my calculator and got 5.44
Nnesha
  • Nnesha
yes looks good
anonymous
  • anonymous
the thing is they don't want decimals and when I inputted 5 it was incorrect. We can't use arcsin here like we did with the previous one right?
Nnesha
  • Nnesha
hmm same mistake again and again you have to include sin cos ratio like 10 sin(33) would be the answer they are looking for
Nnesha
  • Nnesha
no remember when we have to find an `angle ` then we should take arcsin for this question we are need sides not angle
Nnesha
  • Nnesha
side length *
Nnesha
  • Nnesha
that's very important to know
anonymous
  • anonymous
and for b would be 10*cos33=b/10
Nnesha
  • Nnesha
hmm when we need b it self so multiply 10 both sides |dw:1443993995455:dw|

thank you very much!
Nnesha
  • Nnesha
np just don't ever use 90 degree angle !

makes sense :)
