Triangle W X Y is shown. All angles have different measures. Point S is equidistant from each side of the triangle. Lines are drawn from each point of the triangle to Point S. Congruent lines are also drawn from each side to the point to form right angles and form lines segments V S, T S, and U S. Angle S Y U is 39 degrees. Given that point S is equidistant from the sides of ΔWXY, find the following measures. SU = mAngleSYW = ° mAngleWXY = °

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)?
