Question

A tree 90 cm high broke at a point but did not separate. It's top touched the ground at a distance of 27cm from its base.Find the height of the point from the ground,at which the tree broke.​

Answer 1

Answer:

40.95cm

Step-by-step explanation:

Let the height at which tree broke be x

so the part of tree which fell=(90-x)

applying pythagoras theorem,

we get 27^2+x^2=(90-x)^2

729+x^2=90^2+x^2-2×90xx

180x=8100-729

X=7371÷180=40.95cm

THAT'S ALL
