Firefighters need to use a 60-foot ladder to save a child. She is 50 feet above street
mr_godi [17]

Answer:

The ladder must be placed at a distance of 33.2 feet from the bottom of the building

Step-by-step explanation:

From what we have here, we are looking at a right angled triangle with the hypotenuse which is the length of the ladder

The height of the child is 50 feet from ground level

So we need to get the third side of the triangle

We can get this by considering the use of Pythagoras’ theorem

This will give us the length of the third side of the triangle

From Pythagoras’ the square of the hypotenuse is equal the sum of the squares of the two other sides

Let the unknown side be x

Thus;

60^2 = 50^2 + x^2

x^2 = 60^2 - 50^2

x^2 = (60-50)(60+50)

x^2 = (10)(110)

x^2 = 1100

x = square root of 1100

x = 33.166

To the nearest tenth, this is 33.2 feet

What is s in -5(s - 30) = -10?
Veseljchak [2.6K]

Answer:

s = 32

Step-by-step explanation:

First distribute the -5:

-5s + 150 = -10

Add 10 to both sides

-5s = 160

Divide by -5 on both sides

s = 32
