A furniture store offers free setup and delivery services to all points within a 25-mile radius of its warehouse distribution center. If you live 20 miles east and 14 miles south of the warehouse, will you incur a delivery charge? JUSTIFY YOUR ANSWER!

I am confused. I don't know what to dooo

Answers

Answer:

Step-by-step explanation:

you can make a right triangle with 20 and 14. To find the hypotenuse, you add

20² + 14² = h²

400+196 = h²

596<25²

596<625

which is true.

Yes , the person will get free delivery as the person lives in the 25 mile radius.

What is a Right Angled Triangle ?

A right triangle is a triangle with one of its side as 90 degree.

It is given that the person lives 20 miles east and 14 miles south of the warehouse.

The warehouse gives free delivery for people in 25-mile radius

The distance between the warehouse and the house ≤ 25 mile

To determine the distance a right angled triangle is considered

The base is 20 and height is 14 , hypotenuse = ?

Hypotenuse ≤ 25

[tex]\rm \sqrt { 20^2 + 14^2}[/tex] ≤ 25

24.43 ≤ 25

So , Yes the person will get free delivery as the person lives in the 25 mile radius.
