Convert 40 minutes into degrees:

40 / 60 =2/3 add this to 56 degrees:

56 2/3 =Angle A. Use the cos function:

Cos(56 2/3) = Adjacent side / Hypotenuse

Cos(56 2/3) = 22 / c      Take the cos of 56 2/3 degrees.

0.5495 =22 / c                 Cross multiply

0.5495c = 22                    Divide both sides by 0.5495

c =22 / 0.5495

c = 40.0 Feet.
