Question

two poles 15m and 30m highare standing straight on the ground. if their feet are 36m feet apart, find the distance between their tops

Answer 1

Let AB be pole of height 15m
and DC be pole of height 30m


In rt triangle DEB , angleE=90°
By Pythagoras theorem
${36}^{2} + {15}^{2} = {bd}^{2}$
ie
BD=39m

Thus the distance between their tops is 39m
