Illustrative Mathematics: G Srt, G Mg How Far Is the Horizon?

Curated by ACT

Some friends are at the beach looking out onto the ocean on a clear day and they wonder how far away the horizon is. A second problem asks how far the horizon would be from the top of a mountain. Students must also answer a question about the proportionality of triangle side lengths. Aligns with G-MG.A.1, G-SRT.B.5, and G-MG.A.
