Need this now

a 10-foot ladder is leaning against a wall. the base of the ladder is 2 feet from the base of the building. how far up the building does the ladder fall? round to nearest tenth if needed.

5.2
5.4
9.8
13
56

Um..I'm guessing 9.8 but I am not positive.

It is 9.8 because to find the rise you'd need to find the angle between the hypotenuse and run which is cos (cosine which is run/hyp) on the calculator. Divide 2 by 10 and use cos-1 (reverse cosine) on the calculator to get the angle. After that, press the tangent button (tan which is rise/run or slope angle), and multiply it by the run, in this case, that would be 2 and you'd get 9.79 which rounded is 9.8

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
