Question

A ladder 30 m long rests against a wall. If the feet of the ladder is 15 cm away from the wall, then the angle

of elevation of top of ladder from its feet is​

Answer 1

Answer:

ladder length...30m

ladder away from the wall ..15m

then the angle 30-15 ..15

Answer 2

Step-by-step explanation:

ladder length =30 m

ladder feet away from the wall =15m

let the height of wall is x

hypotenuse =(x)^2+(15)^2

30^2=(x)^2+(15)^2

900=x^2+225

x^2=900-225

x^2=675

x=675sqare

x=25.98
