No

Step-by-step explanation:

It depends on the shape of the stage, generally, the stage is cuboidal or cubical in shape, so assuming the stage is cuboidal.

Here, the spotlight has top cover the minimum angle of 90° (for a corner position of the spotlight.

Now, compute how much angles the spotlight can cover.

From its central position, the spotlight can rotate 25° to the left or right, so, angle covered due to rotation is 25°+25°=50°.

As the beam of light from the spotlight can spread 22°.

So, the total angle covered by spotlight= 50° + 22°=72°, which is less than the minimum angle required to cover the entire stage.

Hence, the designer can’t use the spotlight to light each of the objects on the stage.
