Question

If a ladder of length 40m leaning against a wall makes an angle of 30 with the ground then th height from the ground where the ladder meets the wall will be​

Answer 1

Answer:

given:

length of the ladder =40m

angle made by the ladder with the horizontal=30°

Step-by-step explanation:

sin ∅=perpendicular/hypotenuse

perpendicular here is the height of the wall that we have to find

and hypotenuse is the length of the ladder

∅=30°

sin30°=height of wall/length of ladder

sin30°=1/2

1/2=height/40

height of the wall = 20 m
