Answer :
35
Do 28 squared+21 squared and that equals 1225. Then you do the square root of 1225 and that equals 35
Do 28 squared+21 squared and that equals 1225. Then you do the square root of 1225 and that equals 35
By using the Pythagorean Theorem, we will see that Dana and Darlene live 35 miles apart.
Approximately how far do Dana and Darlene live apart?
We can see this as a right triangle where the catheti measure 28 miles and 21 miles.
By the Pythagorean theorem, we know that the square of the hypotenuse is equal to the sum of the squares of the cathetus.
Then the hypotenuse, the distance between Darlene's house and Dana's house, is:
[tex]H^2 = (28 mi)^2 + (21 mi)^2\\\\H = \sqrt{ (28 mi)^2 + (21 mi)^2} = 35 mi[/tex]
Dana and Darlene live 35 miles apart.
