Look at the Schoology problem provided below.

Answer 1

The answer is K= 4 Units

Answer 2

k = 4 units

Explanation:

Using Pythagoras' identity on the right triangle.

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

k² + 7.5² = 8.5²

k² + 56.25 = 72.25 ( subtract 56.25 from both sides )

k² = 16 ( take the square root of both sides )

k =
`√(16)` = 4
