Angle of Depression:  
1) Find the complementary angle of 36.3°:
    90° - 36.3° = 53.7°

2) Find the distance (x) across the the lake (base), given the height (side) of 135 feet opposite the complementary angle of 53.7°:

    Tangent = opposite
                    adjacent
    Tan (53.7°) = 135 feet
                            x
     
     1.3613(x) = 135 feet.
     1.3613x135 feet
     1.3613      1.3613
     
       x = 99.1699 or 99.17 feet is the distance across the lake.
