Question

A 13.5 m fire truck ladder is leaning against a wall.

Find the distance the ladder goes up the wall if it
makes an angle of 43.8° with the ground.

Answer 1

A. because if it is leaning against the wall you’ll find the distance of the ladder which will make an angle of 43.8°

Answer 2

To solve this problem you must apply the proccedure shown below:

1. You have the the 13.5​-m fire truck ladder is leaning against a wall and the ladder makes an angle of 39 degrees 45 ' with the horizontal.

2. Then you have:

39 degrees 45'=39.75°

Sin(39.75°)=d/13.5

d=13.5xSin(39.75°)

d=8.63
