@welshfella

OpenStudy (jacobciezki):

you got a xbox 360

OpenStudy (welshfella):

we know the angle of elevation and the distance on the ground and we need to find the side opposite the angle so that's the opposite and adjacent sides of the triangle so we need the tangent of the angle ( tan = opposite / adjacent)

OpenStudy (jacobciezki):

yea

OpenStudy (welshfella):

so tan 49 = h / 900 h = 900 tan 49

OpenStudy (welshfella):

so grab ur calculator and work that out

OpenStudy (jacobciezki):

yea haa

OpenStudy (welshfella):

ok?

OpenStudy (welshfella):

No what did you get for tan 49 ?

OpenStudy (welshfella):

first find tan 49 - with my calculator you enter tan then 49 but with some you put 49 in first then tan after.

OpenStudy (welshfella):

tan 45 = 1 so you should get a value a bit higher than 1

OpenStudy (welshfella):

lol thats a long decimal - but its correct so multiply that by 900 and you'l have ur answer

OpenStudy (znappydooz):

1,035

OpenStudy (welshfella):

yes

OpenStudy (welshfella):

are you famiilar with the aide to memory SOH-CAH-TOA ?

OpenStudy (welshfella):

sine = opposite / hypotenuse etc

OpenStudy (jacobciezki):

im back

OpenStudy (znappydooz):

Yes, sleepyjess asked me the same XD

OpenStudy (znappydooz):

SOH = Sin(x) = opposite/hypotenuse CAH = cos(x) = adjacent/hypotenuse TAO = tan(x) = adjacent/opposite

OpenStudy (welshfella):

well sorry but i gotta go Znappy hope i've been of some help

OpenStudy (znappydooz):

Alright then... I'll see what I can do XD

OpenStudy (jacobciezki):

can i get a maddel
