Question

a ladder is placed in such a way that its foot is at a distance of 5 metre from a wall and its top richest at window 12 metre above the ground determine the length of the ladder​

Answer 1

Answer:

An atmosphere is a layer or a set of layers of gases surrounding a planet or other material body, that is held in place by the gravity of that body. An atmosphere is more likely to be retained if the gravity it is subject to is high and the temperature of the atmosphere is low.

Correct question:

A ladder is placed in such a way that its foot is at a distance of 5 metre from a wall and its top reaches at window 12 metre above the ground determine the length of the ladder.

Given:

Distance between foot of ladder and wall = $\tt{5m}$

Height of the window from to ground = $\tt{12m}$

Length of the ladder = x

All the things together form a right angled triangle, as given in image.

∴We will solve by using Pythagoras theoram.

Solution:

➞$\tt{x^2}$ = $\tt{5^2}$+$\tt{12^2}$

➞$\tt{x^2}$ = $\tt\sqrt{144+25}$

➞$\tt{x^2}$ = $\tt\sqrt{169}$

➞$\tt{x}$ = $\tt{13}$

Length of the ladder is 13m.
