Question

find the angle made by a ladder of length 5m with the ground if one of its end is 4 m away from the wall and the other end in on the wall​

Answer 1

36 degree.......i hope you will understand

Answer 2

The angle made by a ladder of length 5m with the ground if one of its end is 4 m away from the wall and the other end in on the wall​ is 36.869°

Step-by-step explanation:

Length of ladder = 5 m

Distance of base of ladder from the wall = 4m

We are supposed to find the angle made by a ladder of length 5m with the ground if one of its end is 4 m away from the wall and the other end in on the wall​

So, Hypotenuse = 5 m

Base = 4 m

$Cos \theta = \frac{Base}{Hypotenuse}$

$Cos \theta = \frac{4}{5}$

$\theta = cos^{-1}(\frac{4}{5})$

$\theta = 36.869^{\circ}$

Hence  the angle made by a ladder of length 5m with the ground if one of its end is 4 m away from the wall and the other end in on the wall​ is 36.869°
