For this case, we can model the problem as a rectangle triangle.
 We know the height of the triangle.
 We know the angle between the base of the triangle and the hypotenuse.
 We want to find the base of the triangle.
 For this, we use the following trigonometric relationship:
 tan (70) = 39 / x
 Clearing x we have:
 x = 39 / tan (70)
 x = 14.2 feet
 Answer:
 
The distance between the base of the building and the base of the ladder is:
 
x = 14.2 feet
