Step-by-step explanation:
All you have to do
Is plug in 4 and 12 for X and Y
In a rectangular triangle
.
We have 
Therefore opposite = 3uints and adjacent = 4units.

We need the length of hypotenuse.
Use the Pythagorean theorem:

Substitute:

The distance from his home to his work place is 118.125 miles
<h3>How to find the distance from his home to his work place?</h3>
He drove from home to work at an average speed of 45 mph. Therefore,
speed = 45 mph
let
time = x
speed = distance / time
distance = 45x
His return trip home took 45 minutes longer because he could only drive at 35 mph. Therefore,
45 minutes = 0.75 hours
distance = 35(x + 0.75)
distance = 35x + 26.25
Therefore,
45x = 35x + 26.25
45x - 35x = 26.25
10x = 26.25
x = 26.25 / 10
x = 2.625
Therefore,
distance = 45(2.625) = 118.125 miles
