Question

Tom is afraid of heights above 9 feet. He is asked to repair a side of a high deck. The bottom of the ladder must be placed 6 feet from a deck. The ladder is 10 feet long. How far above the ground does the ladder touch the deck? Is Tom afraid of the height?

Answer 1

• 8 ft
• no

Explanation:

The height on the side of the deck (h) can be found using the Pythagorean theorem. It tells you ...

6^2 + h^2 = 10^2

h = √(10^2 -6^2) = √64 = 8

The ladder touches the deck 8 feet above the ground. Tom is not afraid of that height.
