13 + 7 ! you!

a set of stairs is being built as shown.
the length of each stair is 11 inches. what is the rise, r, for each stair? round to the nearest inch.
2 inches
7 inches
17 inches
24 inches

7 inches

Step-by-step explanation:

Using Pythagoras' theorem on the right triangle, that is

r² + 11² = 13²

r² + 121 = 169 ( subtract 121 from both sides )

r² = 48 ( take the square root of both sides )

r = ≈ 7 in ( to the nearest inch )

only 10/60 isn't equivalent

hope this : )
