Greetings.
By solving an Inequality is almost the same as solving an equation.
We simply move x-term to the same term and the number or rather a constant to the same side.
A quick reminder. If the coefficient for the variable that we want to solve is in negative. For Inequality, moving the negative coefficient for the variable to another side will force the Inequality sign to swap to opposite.

Answer:
52.8 feets
Step-by-step explanation:
From the diagram :
The height of tree woulb be :
Height above the ground (at breakpoint) + hypotenus
Hypotenus, h cab be obtained using Pythagoras rule :
h² = opp² + adj²
h² = 39² + 12²
h² = 1665
h = sqrt(1665)
h = 40.804 feets
Height of tree to the nearest tenth ;
40.804 feets + 12 feets
= 52.804 feets
= 52.8 feets
f(x - n) - shift n units to right
f(x + n) - shift n units to left
f(x) + n - shift n units up
f(x) - n - shift n units down
