Question

A plant which was 90cm high broke at a point in a storm but did not seperate .It top touched the ground at a distance of 27cm from its base .Find the height of the point from the ground at which the plant broke

Answer 1

Answer:

Perpendicular=90 cm

Base=27cm

Let the height of broken point of plant be x

Tan=perpendicular/base

Tan=90-x/27

x=90/27

x=3.333

Explanation:

Answer 2

H²= p²+b²

= (90-x)²= x²+27²

= 8100+x²-180x = x²+729

= 7371/180=x  

X= 40.95 cm
