From a boat on the lake, the angle of elevation to the top of a cliff is 24°52'. If the base of the cliff is 944 feet from the boat, how high is the cliff (to the nearest foot)?

you must realize this relationship, moving sideward and upward. there is a 90 degree angle, common sense, but it must be stated sometimes lol x and y axis are perpendicular because one is horizontal and other is vertical... so on

how do you convert from degrees?
anonymous
  • anonymous
Don't use the Pythagorean Theorem lol. Use tangent.
anonymous
  • anonymous
You are finding the opposite side. You know the adjacent side and you know Theta.
anonymous
  • anonymous
right, so I use tangent to convert 24°52

I understand this but I still don't know how to convert the degree, do you cross multiply or something?
dan815
  • dan815
oh yah lol i dunno why i call it pythagorean, just a habit when i see 90 degree triangle...
anonymous
  • anonymous
What do you mean by "convert" ?
anonymous
  • anonymous
the degree needs to be changed into a regular number right? so I can divide it
anonymous
  • anonymous
No. It does not need to.
anonymous
  • anonymous
so you just divide it the way it is?
anonymous
  • anonymous
Tan(24.51) gives you a "Regular" number.

oh duhhhhhh wow!!! thanks for all the help:)
anonymous
  • anonymous
No problem :) .

Uhh I'm still a little bit confused, for example if you have sin=opp/hyp, then sin(25 degrees)= 13.5/x, then 13.5/ sin(25 degrees), I don't understand how to solve this
dan815
  • dan815
hi lemme teach you
dan815
  • dan815
for any 90 degree angle you can use SOH CAH TOA right
anonymous
  • anonymous
right, I understand that

I think she is asking how do you equate Tan(24.52) degrees.

calculator

Or use the Taylore series ;) . Just kidding. You will learn that later.
anonymous
  • anonymous
yes, I understand this part but I don't understand how to get rid of the degree in this equation, in your calculator do you just put tan(24.51) and solve because it doesn't give the correct answer
dan815
  • dan815
use degrees mode
dan815
  • dan815
use degrees mode and enter tan(24.51) * 944
anonymous
  • anonymous
oh okay, lastly how do you actually find the answer for this equation?

havent u learnt this, how to manipulate equations

I've learned this but I do online school and my teacher doesn't do a really good job of explaining things
