Expert Answer:

let the string length is x for second boy  and sin  θ = string length /  height

as base is same for the boys so for first boy sin 30 = 1/2 = 100 / h   ===> h = 200                                                   and for second boy  sin 45 = x / h - 10  putting value of h we get   1 /  2  =  x / 190 ===> x = 190 / 1.414 = 134.37m
