Question

Three people are sitting on a bus. Harold is directly behind Shawn and directly left of Brooke. If Shawn and Harold are 1 meter apart, and Brooke and Shawn are 2 meters apart, what is the distance between Harold and Brooke? If necessary, round to the nearest tenth.

Answer 1

a²+b²=c² is the equation. You are trying to solve for c in this case.

1²+2²=c²

1+4=c²

5=c² Take the square root of both sides√

√5=c

c=2.2 ft
