so it says the ratio of girls to boys is 7 to 3 but it’s then asking me to fill in the blanks with the right numbers but it’s all sorta confusing like I’m not sure what numbers go into what boxes, the numbers that some boxes go in or our choices are at the top and the ones that are missing numbers are at the bottom.

Option A

Distance of each boat from light house is approximately 20 miles.

Solution:

The diagram of this question is attached below

In the attached figure A and B represents position of two boats and C represents position of light house.

Given that CA = CB and  

So triangle ABC is isosceles triangle with angle

 [Angle opposite to equal side CA and CB]

[Angle sum property of triangle]

Construct a median CE on AB,

AE = EB  [ Since CE is median]

In triangle AEC,

Hence AC that is distance of each boat from light house is approximately 20 miles.
