Answer :
Answer:
They are [tex]10\sqrt{2}[/tex] feet apart.
Step-by-step explanation:
It is given that, You are 20 feet north from your house an your friend is 10 feet north of your house.
The distance between you two in the north-south direction is (20 - 10) = 10 feet.
Similarly, the distance between you two in the east-west direction is (25 - 15) = 10 feet.
The distance between you two is [tex]\sqrt{10^{2} + 10^{2} } = 10\sqrt{2}[/tex] feet.
