Question 1042290
The description is a little bit imprecise, but an interpretation can be made.



A and B are on one side of the river, or on one bank, and C, the house is on the other side of the river  (the opposite river bank.);  Length AB is 230 meters; angle BAC is 48 degrees; angle ABC is 62 degrees.


Sum of measures of interior angles of a triangle must be 180 degrees, so you can determine at angle C that   angle BCA measures {{{180-48-62=highlight(70*degrees)}}}.


Use Law Of Sines with the given and the found information:
{{{AC/sin(62)=AB/sin(70)=BC/sin(48)}}}


and AB was given as 230.
{{{highlight(AC/sin(62)=230/sin(70))}}}

I'm finding {{{AC=216}}}, but you can recheck this (referring to the formula solution).
