suppose you live 6.7 miles from a hill. From your home you can see a plane directly above the hill. your angle of elevation to the place is 30 degrees. what is the plane's altitude?
|dw:1428313952413:dw|
what information do you have? you have, the adjacent side and one angle
You are asked to calculate the altitude (i.e. the opposite side)
Well you know, tan = opposite side/adjacent side, right?
yes
so we would need to plug in the terms?
Tan 30 = 0pposite/ 6.7
Therefore, opposite = Tan 30 degrees x 6.7
use your calculator: Tan 30 degrees =0 .5777
i did but i got -6.40
0.5777 x 6.7 = 3.86
Enter this: tan, 3, 0, equals, what do you get?
i used my other one and i got that answer! thank you so much!
good woman!
Its nice, when you can help someone!
yes it is :)
