Question

answer this and be the brainliest A ladder 20m long is kept inclined to reach a window 16m high. How far from the wall should the foot of the ladder rest?of the ladder rest?

Answer 1

answer: distance from ladder to wall is 12 m.

Step-by-step explanation:

it seems like a right angled triangle.

according to question

ladder's height is 20 m and wall' height is 16m.

we name the triangle as ABC where AB=16m ,BC=20m and CA =?

we assume CA = X m.

so , by pythagorus property,

BC^2 =AB^2 + CA^2

20^2 =16^2 + x^2

400 = 256+x^2

we subtract 256 to both side for solving equation

we obtained : 400-256=x^2

144=x^2

12=x =CA

• so length from ladder to wall is 12m.
• Hope you understand.

Answer 2

Answer:

the distance from the ladder to the wall is 12cm
