Question

the proper angle for a ladder is about 75 degrees from the ground. Suppose you have a 6 feet ladder. How far from the house should you place the base of the ladder

Answer 1

Draw a picture and recognize the right angle! Therefore, the sum of the other two angles is 90. Therefore, the most acute angle is 15. If you know the hypotenuse, 6, then you can solve the other two sides using trig.
