Math Is Fun Forum

so im gonna do (b) first and so im gonna use TOA because i know the adj and opp and im trying to find the angle so the formula for tan is Opp/Adj = Tan(x) so to replace the vars it would be 213/1200 =  Tan(x) now i figure out what the tan of x equals and it would be 0.1775 so now i click Tan-¹ which equals 10.06 so the x angle equals 10.06°(not rounded) now to (a)

So im gonna use the formula that bob bundy gave me Adj/Cos(angle) = Hyp so replace the vars and i get 1200/Cos(10.06) = Hyp so the hypotenuse equals 1218.75m

am i right?

well gtg now for today bye

ya but what does x equal? oh thats an equivelent fractions *bonks head on desk* ok so x = the sqrt of 30000 right?

huh? i dont get that?

ok so im gonna use tan and the equation is O/A = Tan(x) so replace the vars so 10000/A = Tan(30) so im gonna find the true value of tan(30) which is 0.577(rounded) then i do 10000/0.577 which equals 17320.5 so now im gonna double check my answer so i do 10000/17320 which equals 0.577 and then i click tan-¹ and get 29.99 which is really close to 30 so the distance that the plane has to go is 17320.5 m until it reaches the costline

when i click on the link i cant read whatever it says its all symbolish nonsense D:

i cant read the doc? what program do you use to open it?

D: help plz ive tryed but when i double check it never works could you give me which one i should chose sin cos or tan? plz

soo any time now

k thanks bob bundy

it did ask for centimeters? well ok sorry about that if i focus too much on one thing i forget another (like i work too much on the problem and i forget the label
)

ok so the x = 6.44
