Susan wanted to measure the height of her school’s flagpole. she placed a mirror on the ground 72 feet from the flagpole, then walked backwards until she was able to see the top of the pole in the mirror. her eyes were 5 feet above the ground and she was 12 feet from the mirror. using similar triangles find the height of the flagpole to the nearest foot. a. 25 ft. b. 30 ft. c. 55 ft. d. 60 ft.

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.
