If you have a 10 foot ladder and you put it against a wall at the ideal angle, how high on the wall will the ladder touch. Assume a 90 degree angle between the wall and the floor.
Please use complete sentences and include the trig. calculations to the best of your ability.
the full length of the ladder is 10 feet, there is 3 feet above the roof, so the distance from the ground to the top support is 7. x=7 the hypotenuse is 7, the short leg is 7/4, so the height (the other leg) is: h=√[7²-(7/4)²]=(√15)*7/4=6.7777 feet
