normally I wouldnt post anything like this here but if I dont get these two pages done by monday I cant take my exams, its not really hard questions I just always forget how to do them.........
If a 6-metre ladder is leaning against a wall, the angle formed by the ladder and the wall is 25 degrees ,how far is the base of the ladder from the wall?
,how far up the wall does the ladder reach?
If someone could show me how to get these answers on my calculator or whatever that'd be great thanks.
k I figured that one out but now im stuck on this one lol
if a plane is flying at an altitude of 10km, you spot the airplane at an angle of 55 degrees to the horizontal...determine the distance the airplane is from you
this is trigonmetry isnt it? do you know soh cah toa?
you solve for x
x is the distance you are from the plane
tan 35 = x/10
or
tan 55 = 10/x
id solve it for you but then i dont have a calculator:smokin:
so I put in tan55 times 10?? lol I cant figure this out
you dont know how to solve a basic equation. okay
solve the first one tan 35=x/10
punch in your calculater the tan of 35 get the answer and multiply it by 10 and that should be your answer
get a book and do it urself...
42...The answer to life,the universe and everything!!
oh by the way....4.75 Meters up the wall,1.25 Meters away from the wall,I Think...
Come on man. That was too easy.
math tis fun.
