The glide slope is the path a plane uses while it is landing on a runway. the glide slope usually makes a 3º angle with the ground. a plane is on the glide slope and is 1 mile (5280 feet) from touchdown. use the tangent ratio and a calculator to find ef (the altitude of the plane) to the nearest foot. the plane is feet high. (enter only the number.)

the altitude of the plane to the nearest foot is, 277 feet high

Step-by-step explanation:

Using tangent ratio:

As per the statement:

The glide slope usually makes a 3º angle with the ground.

⇒

A plane is on the glide slope and is 1 mile (5280 feet) from touchdown.

⇒Adjacent side= DF = 1 mi = 5280 feet.

We have to find the EF.

Using tangent ratio:

Substitute the given values we have;

Multiply both sides by 5280 we have;

⇒

Simplify:

EF = 276.713074614 feet.

Therefore, the altitude of the plane to the nearest foot is, 277 feet high

reduce the friction between its moving parts

step-by-step explanation:

in fact, by reducing the friction between the moving parts of the machine, it is possible to reduce the energy wasted due to this friction; therefore, more input energy is converted into useful work, and this will improve the efficiency of the machine.
