distance between the two boats
Let AB be the light house and the two boats be at C and D
AB = 100 m
tan30° = BC/AB | BC = tan(30) * 100 = 57.7350
BC = 57.7350 m
tan45° = BD/AB | BD = tan(45) * 100 = 100
BD = 100 m
Therefore, the distance between the two boats is = BC+BD
= 57.7350+ 100
= 157.73 m

IF you find Both 2 Boat Distance from light house
AB2 + BC2 = AC2 || Square root(1002 + 57.73502 ) = 115.47 || AC = 115.47
AB2 + BD2 = AD2 || Square root(1002 + 1002 ) = 115.47 || AD = 141.42
