Answer:
<h2>34.88feet</h2>
Step-by-step explanation:
The set up forms a right angle triangle with the length of the ladder being the hypotenuse and the angle of elevation is 29.32°. USing SOH, CAH TOA to determine the distance of the building from the base of the ladder.
The distance we are looking fir will be the adjacent. According to CAH.
cos29.32°= x/40
x = 40cos29.32°
x = 34.88feet (to the nearest hundredth)
The ladder is 34.88feet away from the building
Ф = 3π/4. Transform it into Rectangular (or Cartesian) form .
The coordinates of Ф are x ,y in rectangular form ==> so:
tan(Ф) = y/x and y=x . tan(Ф) ==> y= x. tan(3π/4). we know that tan(3π/4)= - 1
Hence y = - x
25mm is the same as 2.5cm.
