Answer:

  33.8 cm

Step-by-step explanation:

You want to know a 28 cm ladder's height above a table if its base is 9 cm above the table and 13 cm away from the wall.

Missing leg

The Pythagorean theorem tells you the missing leg of the right triangle is ...

  b = √(c² -a²) = √(28² -13²) ≈ 24.8 . . . . cm

Then the height above the table is ...

  9 cm + 24.8 cm = 33.8 cm

The ladder extends to 33.8 cm above the table.
