    alright tan theta = what ? in general like cos = adjacent /hyp

    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 =

    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

    I believe so, because I tried to put in sin 33 in the calculator but the answer came out wrong

    so I multiplied 10*sin33 inputted that into my calculator and got 5.44

    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?

    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

    no remember when we have to find an `angle ` then we should take arcsin for this question we are need sides not angle

    and for b would be 10*cos33=b/10

    hmm when we need b it self so multiply 10 both sides |dw:1443993995455:dw|

    np just don't ever use 90 degree angle !
