[HELP ME PLEASE] Mai is playing a game with a class of second graders. Mai knows she is exactly 120 inches from the mirror on the floor. She has students stand so that she can just see the top of their heads and then guesses their heights. The students are amazed! How is Mai so accurate? What is the height, h, of the students? ( Don't worry about the next one) If you give an explanation, I'll give you brainliest!
