A linear function is one whose highest power is one (e.g y = mx +c)
A non linear function is one that has powers greater than one (e.g quadratic equations (highest power = 2), cubic equations (highest power = 3), quartic equations (highest power =4))

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.
