There is a 5 feet wide lane. Both walls of the lane are perpendicular to the ground. Two ladders, one 13ft long and other 15ft long, are propped up from opposite corners to the adjacent wall, forming an X shape. Each ladder is so placed that one end of the ladder touches the corner while the other end touches the top of the wall facing it. The two ladders are also touching each other at the intersection of the X shape. What is the distance from the point of intersection to the ground?
a. 6.5 feet
b. 5/sqrt2 feet
c. 7 feet
d. None of these
i am getting 6.48
means 6.5 as the ans
is that correct?????????
n/a
solutions pls?
the correct answer is 6.96 feet that is roughly equal to 7 feet hence option c
note : answer will be correct if taking approx. value is allowed as it can be seen 6.96 is never equal to 7 and there is an option none of these that can also be given if approximation is not allowed.
I think answer is 6.5 ft
