This was a great task for communicating the connection between triangle similarity and right-triangle trigonometry. It takes time for kids to get there, but when they do, it takes away the "mystery" of the numbers their calculator gives them when they press those strange sin, cos, tan buttons. Nice!

CCSSHSG-SRT.B.5
Use congruence and similarity criteria for triangles to solve problems and to prove relationships in geometric figures.
CCSSHSG-SRT.C.6
Understand that by similarity, side ratios in right triangles are properties of the angles in the triangle, leading to definitions of trigonometric ratios for acute angles.
