Answer 1

Answer:

Step-by-step explanation:

n the first figure and from triangle BCD

    sin30 = BC/BD

=>1/2 = 1.5/BD

=> BD = 1.5*2

=> BD = 3

So length of slide for child below 5 years = 3 m

Again in the second figure and from triangle BCD

    sin60 = BC/BD

=>√3/2 = 3/BD

=> BD = (3*2)/√3

=> BD = (√3*√3*2)/√3

=> BD = 2√3

So lenght of slide for child greater than 5 years = 2√3 m
