Two boats are on the water at points A and B, and a lighthouse is located at point C. The three points form a triangle, where BC = 24 kilometers, m_A = 90°, and m_B=45°. Leaving your answer in simplified root form, what is the
distance between the boat at point A and the lighthouse?

There are two major tests of readiness for college: the act and the sat. act scores are reported on a scale from 1 to 36. the distribution of act scores in recent years has been roughly normal with mean µ = 20.9 and standard deviation s = 4.8. sat scores are reported on a scale from 400 to 1600. sat scores have been roughly normal with mean µ = 1026 and standard deviation s = 209. reports on a student's act or sat usually give the percentile as well as the actual score. the percentile is just the cumulative proportion stated as a percent: the percent of all scores that were lower than this one. tanya scores 1260 on the sat. what is her percentile (± 1)?
