Ah, the internet. Where men are men, women are men, and children are the FBI.
x*tan(35) = y
(5+x)*tan(55) = y
( both of these given from the triangle)
set the two equal to each other
(5+x)tan55 = xtan35
xtan55 - xtan35 = -5tan55
x = (-5tan55)/(tan55 - tan35)
assuming you can plug into a calculator, do so.
once you get x, plug back into the first equation.
(-5tan55)/(tan55 - tan35)tan35 = y
there you go.
EDIT: All this is assuming this is a right triangle. Didnt read the problem all too well.
