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

Step-by-step explanation:

given lenght of ladder=40 m

it make angle with wall =30°

let height of wall= h

sin30°=h/40;

1/2= h/40;

h= 40 * 1/2

h=20 m

Answer 2

Answer:

20m

Step-by-step explanation:

ladder=40m

angle of elevation=30

sin0=P/H

=> 1/2=P/40

=>40/2=P

=>P=20M

i.e, Height of wall =20m
