Question

9. Due to strong wind, a part of tree 18 m high broke at a distance of 5 m from the ground, without separating from the main stem, top of the tree touched the ground. At what distance from the foot of the step did the top of the tree fall on the ground? ​

Answer 1

Answer:

The part of tree broke is 18m

The distance from foot to tree top is 5m

h=?

here we should use the Pythagoras theorem

18²=h²+5²

324=h²+25

324-25=h²

299=h²

h=√299
