you know that for such a triangle, the sides are in the ratio
1:√3:2
So, the short side is 41
The long side is 41√3
The hypotenuse is 41*2
The functions of 30° are standard values, which it would be well to learn.
A building lot in a city is shaped as a 30° -60° -90° triangle. The side opposite the 30° angle measures 41 feet.
