You are lying 120 ft away from a tree = Base of a Right Angled triangle
a tree that is 50 feet tall = Height of a right Angled triangle....

Ignore the 0's in 120 & 50 , and recall the pythagorean triples, the hypotenuse will be 13 or 130 as the pythegorean triple is ( 5 , 12 , 13) Answer must be (D)

How far is war from top of the tree in straight line = sqrt(50^2+120^2) = 130

IMO D

Hi SajjadAhmad,

Can you please clarify what do you mean by "....how far is your hear from the top of the tree". Did you mean " hair"?

Hello stne

You are overthinking on this question, this is very easy 500 level Geometry question. Don't get confused by wording see below image.

Use pythagoras theorem formula

\(a^2 + b^2 = c^2\)

or simply its a pythagoras triplets

3,4,5
5,12,13

And D is the answer

Hope it helps

Hi SajjadAhmad,
I did not mean to offend you in any manner. It is not only about getting questions correct but also about posting quality questions without any error. I wanted to point out that the word " hear" seems out of place and does not make sense in the context.
Can you point out what " hear " means in this question? Perhaps I am missing something ?
