Answer 1

Hola

Your answer:

Let A = 3x

Let B = 5x

I took this by the given ratio

Dividing A/B = 3/5

Formula of resultant = $\sqrt{A^2+B^2+2ABcos\theta}$ = $\sqrt{(3x)^2+(5x)^2+2\times 5x\times3x\times cos60}$ = $\sqrt{9x^2+25x^2+15x^2}$ = $\sqrt{49x^2}$ = 7x = 35

So, x = 35/7 = 5

A = 15

B = 25
