A 9 foot ladder liens against the side of a house how far is the bottom of the ladder from the side of the house when the angle of elevation of the latter is 75 class=

Respuesta :

Answer:   2.3

==========================================

Work Shown:

cos(angle) = adjacent/hypotenuse

cos(75) = x/9

x = 9*cos(75)

x = 2.32937140592269

x = 2.3

The bottom of the ladder is about 2.3 feet from the bottom of the house.
