Arnel wanted to measure the height of his school’s flagpole. He placed a mirror on the ground 50 feet from the flagpole, then walked backwards until he was able to see the top of the pole in the mirror. His eyes were 5.4 feet above the ground, and he was 10 feet from the mirror. Using similar triangles, help Arnel find the height of the flagpole.

Agroup of students want to create a garden. they do not know the exact measurements but they propose using a variable to represent the length and width of the garden. the length of the garden is 10 feet longer than double the width. use a single variable to write algebraic expressions for both the length and width of the garden. write an algebraic expression for the area of the garden. use mathematical terms to describe this expression.
