Question

Lyra and Donna are testing the two-way radios they built for their high school science project. Lyra goes to the top of a building that is 22 meters high with one of the radios and stands directly above the building’s entrance. Donna walks out of the entrance, perpendicular to the building, with the other radio. If Donna is more than 50 meters from the entrance, the connection between the radios breaks. What is the range of communication for the two radios to the nearest meter?

50 meters

55 meters

Even though the building is not going to be a triangle, that's the shape you get when you set up the problem. The 22 is the height of the building and the 50 is how far away the other girl can walk from the building before they lost connection.
