A 22-ft ladder leans against a building so that the angle between the ground and the ladder is 70°. How high does the ladder reach on the building? (Round your answer to the nearest foot.)

The value of height does the ladder reach on the building = 21 ft

Explanation:

length of the ladder = 22 ft

Angle between the ground and  the ladder = 70°

Now we have to calculate ( h ).

From the triangle ABC ,   =

⇒ h = × 22

Put the value of = 70° we get,

⇒ h = 70° × 22

⇒ h = 21 ft

This is the value of height does the ladder reach on the building.

hello there!

your answer is a “generator”

a generator does not create energy but instead it transforms it.

it’s basically a motor working in reverse.
