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 bottom of the building?

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

The figure is of right angled triangle

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 =

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

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.
