Hello!
This makes a triangle
The cat is 20 ft high
The triangle is 20 feet high
The is 6 ft between the ladder and the tree
The base is 6 ft long
You use the Pythagorean theorem to solve this

a and b are the base and height
put in the values you know

square the numbers
36 + 400 =

Add
436 =

Take the square root of 436
20.9 = c
Since this is lower than the length of the ladder the ladder is long enough
The answer is yes
Hope this helps!
Solve it like a normal equation, but with < instead of =
9k - 2 < 3k + 10
