To hang lights on his house, Miles placed a 12 foot ladder 3.5 feet from the base of his house. How high up will the ladder reach? ((Pls explain!***))(It's related to triangles)

29. because you will divide each number of months by 12 to find the number of years. which would mean, 5, 12.5, 16, 45, 50, 72.5. which is crazy. anyhow, i think you find the median in the middle. and yea hope your test goes good
