A 30-ft ladder leans up against the side of a building and just reaches a ledge on the building that is 20 feet above the ground. Find the angle the ladder makes with the ground, to the nearest hundredth of a degree.
We knpw an opposite side(20) ......the ladder forms the hypoteneuse of right tringle... we can use the sine inverse to find this
Sin-1(20/30) = about 41.81 degrees
