Find three numbers in the ratio 2:3:5, the sum of whose squares is 608 |
|
Answer» Step-by-step explanation: LET the three numbersa, b, c, be 2X, 3x, 5x. we know that (2x) ^2+ (3x) ^2 + (5x)^2= 608 4x^2 + 9x^2 + 25x^2 = 608 38x^2 = 608 x^2= 608/38 x^2=16 x= √16 x= 4 a= 2x = 2*4=8 b=3x= 3*4=12 c = 5x= 5*4=20 Therefore, the three numbers are 8,12,20 |
