Answer:
Step-by-step explanation:
It's close, but not close enough to be at least 10 feet above the ground. This is a classic right triangle trig problem. We have the length of the ladder, which is the hypotenuse of the right triangle, to be 11 ft. The base angle, or the angle of inclination, is 65. We are looking for the height up the wall that the ladder will go at this angle. The height of the wall is the side opposite the base angle, so the sin ratio applies here.
[tex]sin65=\frac{y}{11}[/tex] and
11 sin(65)= y so
y = 9.96938 ft
Again, close but not quite there.
