have u tried anything ?? :=) i'm sure u did
yea so I used tan90=10/b
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 =
|dw:1443993462650:dw| so yes that's right
use calculator for sin (33)
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
hmm what do you mean wrong ?
what did you get ?
so I multiplied 10*sin33 inputted that into my calculator and got 5.44
yes looks good
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
side length *
that's very important to know
and for b would be 10*cos33=b/10
hmm when we need b it self so multiply 10 both sides |dw:1443993995455:dw|
thank you very much!
np just don't ever use 90 degree angle !
makes sense :)
