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.

i just did an experiment like this in my science class. also the answer is yes, it will get separated because they are two opposites meaning if they are opposite they can not attract.

hope this .!
