• A ladder of length 5 m is placed against a vertical wall with its foot 1.8 m away from the base of the
wall. How far up the wall does the ladder reach?​

Step-by-step explanation:

length = 5 m

height = 1.8 m

The triangle that it formed is given in the figure,

Now first we have to find angle A,

sin(A) =perp/hyp = 1.3/5 = 0.26

now we get ,

Angle A = 15 degree

now using ,

tan(15) = perp/base = 1.3/distance

distance = 1.3/tan(15)

distance =1.3/0.27

distance = 4.8 m

sorry i just need to anwers this to get points
