@Akshit.
In this problem there are two bases and to perpendiculars h^2 = (10 + 2)^2 + (2 + 3)^2.
=> h= root of 12^2 + 5^2.
=> h = root of 169.
So, h= 13.

Using Pythagoras theorem.
AC+CE = AE required solution.
To find AC, CE ?
(AC)^2 = (2)^2+(10)^2 = Square root of 104 = 10.19.
(CE)^2 = (3)^2+(2)^2 = Square root of 13 = 3.6.
So AC+CE = 13.79. But option gave 13.
Hope all of you got it.

I want to say you that Pythagoras theorem says h^2 = p^2+b^2.
Therefore, h^2 = 10^^+2^2.
= 100+4 = root of 104+16 = 120 and this is not a perfect square.
So the answer is none of these.

A taxi driver commented his journey from a point, and drove 10km towards north, and turned to his left and drove another 5km. After waiting to meet a friend here, he turned to his right and continued to drive another 10km. He has covered a distance of 5km to East then, in which direction would he be now.

I want in which direction he is from starting point.

Answer please.
A man faces south and walks 10 km, turn west and covers 4 km, then turn north and covers 7 km, how far is from the starting point.

I agree with @Kiran point. Please if someone have the right conceptual clarity. Then explain the dissonance in the two thought over this questions.

Pythagoras is the correct method.

Now which 1 method is correct, by calculating using Pythagoras or by calculating the distance in same direction?
