Kali has a 6 centimeter ladder and puts the base of the ladder 2 meters away from the tree how high into the tree will the lader reach

I am going to assume ‘centimetre’ was a typo.

A^2 + B^2 = C^2

C^2 - A^2 = B^2

32 = B^2

Square root both sides

B = 5.7m high

The ladder will reach 5.7 meters high

What’s the question?
