A man walks 5 meters north from his house, turns left 9 0 ∘ , walks 12 meters further and reaches a park. How far, in meters, is the park from his house?

Christ, ask me a simple maths question, or at least a straightforward one, if you want to get cocky, let's start to talk about the English language
Why make it so complicated?
I think a lot of people instead of answering how far the park is from his house, are answering how far he walked to the park from his house and are assuming they're the same.
You didn't specify what units to express our answer in... I could say 1300 centimeters and it should also be correct.
Correct Lee Isaac.
Its using meters as measurement so you would have to follow inn suit
I was going to say that 13 is wrong as well, it has to have units.
Doesn't everyone know their Pythagorean Triples? ;)
Yes, 3,4,5 5,12,13 :D
apply the PYTHAGOREAN theorem..
x=sqrt(12^2+5^2)
Using Pythagoras theorem, square root of 12^2 + 5^2 gives 13
Where is the office? We didn't cm across any thing said abt office in the question... At first question is itself wrong
the man walks to park from his house. where does the office come from???
totally wrong question....:/

A perfect problem where a beginner can test his attentiveness and smartness.
Then first please edit that thing and correct it kindly
It is displacement, not distance
It can solve by using simple vector equation I.e ( resultant vector )
I'm just wondering if there's a specific name for this one. I remember calling the 3-4-5 right triangle combination an Egyptian triangle
it makes a shape of triangle. √12²+25²=13
This problem is according to the Pythagoras theorem,
bad question. why assume park did not extend further south. distance could have been 12m assuming ll lines and park starting min of 5m south of walkers intersect.
Simple use of Pythagoras's theorem .
a^2+b^2=c^2 5^2+12^2=c^2 25+144=c^2 169=c^2 13
Just use Pythagorean Theorem. It's very easy!
Required distance is radical of 144+25 which is equal to 13 meter
The Pythagorean theorem, which shows a 2 + b 2 = c 2
So 1 2 2 + 5 2 = 1 4 4 + 2 5 = 1 6 9 , then the square root of 1 6 9 is 1 3
suared? how is it? please answer my quistion cause icant sleep on it

A turn represents, basically, a 90 degree angle.
a squared + b squared = c squared.
5 squared + 12 squared = c squared.
25 + 144 = c squared
169 = c squared
c = 13
Also, (5,12,13) is a Pythagorean Triple. It's easily identifiable. As such with (3,4,5), (8,15,17) and (7,24,25). Anyways. yeah.
This is solved using the Pythagoras Theorem. So (5 squared) + (12 squared)= Distance from the park squared. 25+144=169. The square root of 169 is 13. So 13 is the answer.
Sorry Clavin, but strictly speaking, your answer is only approximate. In fact, we on the surface of the earth need to practice spherical trigonometry to solve problems like this "exactly". Sure, the error is small, but approximating a spherical triangle with a plane triangle is still an error... Remember that in a spherical surface geometry, there are no parallel lines (all lines meet eventually), straight lines are great circles, and angles of a triangle sum to more than 180 degrees.
use phythagorean theorem, c2=a2+b2 , 0r c=square root of a2+b2
No one said that the left he took is perfectly normal (90 degrees)

If the direction was other than perfect notmal, it would have been specified.
i try physics to solve this problems using the resultant vector .. and it's effective.
you are great bro!
Pythagorean Theorem. Formula: c^2 = b^2 + a^2 [where c is the hypotenuse, and b and a are the legs]
Solution:
c^2 = 5^2 + 12^2
c^2 = 25 + 144
c^2 = 169
/sqrt c^2 = /sqrt 169
c = 13
It is triangle with two sides of 5 and 12 meters and 90 degree angle.by pythogorous calculations,we get distance of park from his house 13 Meters ans.

simple pythagoras theorem.
5 ^2 + 12 ^2 = 169 ( 13 ^2). So the answer is 13
\sqrt{25+144} = 13
simple trignometry:.pythagoras theorem
It's just about using squares and roots

One can make use of the Pythagorean Theorem for right triangles.
Let the length of the side (of the triangle) be 5 meters and the length of the base (of the triangle) be 1 2 meters.
Required distance
= 1 2 2 + 5 2
= 1 6 9 = 1 3 .
