Question

The top of a 12 foot ladder, leaning against a building, makes contact with the building 9.6 feet above the ground. What angle does the ladder make with the ground?

Answer 1

53.13 degrees.

Since this is a right triangle, you would draw a picture with 12 as the hypotenuse and 9.6 up against it. To find the angle, you would do the arcsine of (o/h), or (9.6/12).

This gives an answer of 53.13 degrees.
