When you love something you become very good at it.

In this case ypu a wall, the ground, and a ladder. The ladder is 28ft and you need the distance from the wall to the bottom of the ladder in order for the ladder to make a 75°angle with the groud

Imagine the triangle

The length of the lader is the hypotenuse cos (@)=adj/hyp=n/28 where n is the distance fron the wall to the bottom or base of the ladder

Cos (75)=n/28 then n=cos (75)×28...
