A 1-story community hospital has the shape of a right triangle with the sides measuring 119.62 meters, 110 meters and 47 meters. The owners will construct a new aisle perpendicular to the hypotenuse coming from the right angle. What will be the length of the new aisle?
Angle between the sides measuring 119.62 and 110 meters can be obtained thus
cos theta = 110 / 119.62 = 0.9196
Theta = arccos(0.9196) = 23.13
Let the length of the new aisle be x, then
sin 23.13 = x / 110
x = 110 sin 23.13 = 43.2 meters.
