Question

A b ratio c is equal to 2 ratio 5 ratio 7 then find the ratio of a square + b square ratio b square + c square

Answer 1

Answer:

13 : 58

Step-by-step explanation:

a:b:c = 2:3:7

let a = 2x , b = 3x,c = 7x

Then,

a^2 + b^2 = 4x^2 + 9x^2 = 13x^2

b^2+c^2=9x^2 + 49x^2 = 58 x^2

a^2+b^2 : b^2+c^2 = 13 x^2 / 58 x^2

= 13:58
