Answer:
The correct answer is 7.4 ft
Step-by-step explanation:
It is given that,
A tower has height 94 feet. The angle of depression from the top of tower to the ground is 85.5
The pictorial representation is attached with this answer.
We have to find the distance from base of tower to the key
From the figure we have to find AC
<u>To find AC</u>
AB = 94 ft
<C = 85.5
tan C = AB/AC
tan(85.5) = 94/AC
AC = 94/tan(85.5)
AC = 7.4 ft
