Can someone help me with this problem:)

Answer:

Therefore,

93.6 feet tall is the tower from the ground.

Step-by-step explanation:

Given:

x = Opposite side to angle 60

50 ft = Adjacent side to angle 60

7 ft =  height of boy

So Height of the tower will be,

Height\ of\ tower=x+7

To Find:

Height of the tower = ?

Solution:

In Right Angle Triangle , Tangent Identity we have,

\tan 60= \dfrac{\textrm{side opposite to angle 60}}{\textrm{side adjacent to angle 60}}

Substituting the values we get

1.732= \dfrac{x}{50}\\\\x=86.6\ ft

Substituting "x"  For Height of tower we get

Height\ of\ tower=86.6+7=93.6\ ft

Therefore,

93.6 feet tall is the tower from the ground.
