Write an equation to describe the situation using h as the original height of the helicopter.

Answer 1

Equation
Let the original height of helicopter be x
x-123=309
x=123+309
x=432m

Therefore original height of the helicopter is 432m above the ground.

Answer 2

the original height of the​ helicopter=432 meters ; h-123=309

Explanation:

the original height of the helicopter = h [Given]

now,

helicopter descends 123 meters

so, h-123

to be 309 meters above the​ ground

so, h-123=309

=>h=309+123

=>h=432
