Question 211054: the angle os elevation of a 15ft laddar is 70 degrees. Find out how far the base of the laddar is from the wall.
Answer by RAY100(1637) (Show Source):
You can put this solution on YOUR website! Let x = distance from wall
.
rough sketch shows,,cos 70 = x / 15,,,,x= (cos 70) * 15 = 5.13 ft
.
check,,,cos 70 = 5.13/15 = .3420,,,,ok
.
