Question

Aladin 37 metre long reaches a window which is 12 metre above the ground on one side of the street keeping at fort at the same point the ladder is turned to the other side of the street to reach the window at height of 35 metre find the average of the street?!???!???!!?!!!

plz if you tell the and I will follow you​

Answer 1

The width of the street is 47 m.

In ΔXCY,

∠Y = 90°

XC² = XY² + CY² (By Pythagoras theorem)

CY² = XC² + XY²

CY² = 37² - 12²

CY² = 1225

CY = 35 m

Now, In ΔABC,

∠B = 90°

BC = 12 m (By Pythagoras theorem)

Therefore, the width of the street BY = BC + CY

                                                              = 35 + 12

                                                              = 47 m
