Question 285922
5 x and 13 is a classic 5,12,13 right triangle.
but we aren't told where the right angle is
the legs might be 5 and 13. 
we aren't told where angle L is either.
So there isn't enough info to pin it down though I am betting on 5,12,13
Since there is  right angles we can pin it down to a few sides.
5^2+13^2=h^2
25+169=h^2
194=h^2
h=sqrt(194)=abt 13.9

so we could use sin cos and tan to find angle L if we knew where it was.
