If you place a 50-foot ladder against the top of a 14-foot building, how many feet will the bottom of the ladder be from the bot
tia_tia [17]

Answer:

The measure of bottom of ladder from bottom of building is 48 .

Step-by-step explanation:

Given as :

The length of the ladder = l =  50 foot

The height of the building = h = 14 foot

Let The measure of bottom of ladder from bottom of building = x foot

Now from figure

<u>The figure is of right angled triangle</u>

So,

Hypotenuse² = perpendicular² + base²

Or, OB² = AB² + OA²

Or, OA² = OB² - AB²

Or,  x² = (50)² - (14)²

Or,  x² = 2500 - 196

Or,  x² = 2304

∴  x = \sqrt{2304}

I.e x = 48

So,The measure of bottom of ladder from bottom of building = x = OA = 48 foot  .

Hence, The measure of bottom of ladder from bottom of building is 48 . Answer
