Question

A skateboard ramp is in the shape of a right triangle. What is the height of the
ramp?

Answer 1

A. 12

Explanation:

Answer 2

A

Explanation:

Since the triangle is right use Pythagoras' identity to solve for height (h)

The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is

h² + 9² = 15²

h² + 81 = 225 ( subtract 81 from both sides )

h² = 144 ( take the square root of both sides )

h =
`√(144)` = 12 → A
