Question

a man stand at distance of 8m from the base of a lighthouse of height 15n. find out the distance between his feet and the top of the light house?

Answer 1

This question can be done with the help of Pythagoras Theorem.

Let base be 8m from the man and height be 15m.

Let base be BC and height be AB and hypotenuse be AC

According to the question:

or AC^2= AB^2+BC^2

or AC=  √ (225+64)

or AC=  √ 289

or AC=   17
