There is a way to estimate the height of a tree without having to climb it with a tape measure. Instead, place a
mirror on the ground and stand where you can see the reflection of the top of the tree in the mirror.
1: Use this example to demonstrate:
Points M and G are labeled and represent the Mirror and the point where the tree touches the ground.
a: Label points: T at the top of the tree, E at the person’s eye level, and F at the person’s feet
b: Explain how you can create two similar triangles using the AA similarity postulate. You can sketch the triangles
separately if you would like (hint: if the person and tree stand up straight, they form 90-degree angles at the
ground):
c: If EF = 60 inches, FM = 80 inches, and MG = 200 inches, how tall is the tree? Show all work:

Two language majors, anna and megan, took exams in two languages. anna scored 85 on both exams. megan scored 74 on the first exam and 85 on the second exam. overall, student scores on the first exam had a mean of 82 and a standard deviation of 4, and the second exam scores had a mean of 71 and a standard deviation of 13. a) to qualify for language honors, a major must maintain at least an 85 average across all language courses taken. so far, which of anna and megan qualify? b) which student's overall performance was better?
