Question

Tan15*tan20*tan70*tan75

Answer 1

Step-by-step explanation:

Given that three numbers are in ratio 1 : 2 : 3

Let the three numbers be 1x, 2x , 3x

To find: the numbers

Also given that sum of cubes of numbers is 4500. So we can frame a equation as:

sum of cubes of numbers = 4500

Let us solve the above expression for "x"

Taking cube root on both sides,

Thus the three numbers are:

1x = 1(5) = 5

2x = 2(5) = 10

3x = 3(5) = 15

Thus the three numbers are 5, 10 and 15
