Final: The Shadow
Part of the Triangles section of Coddy's Geometry journey. Lesson 62 of 63.
A statue stands on top of a 6 m column. On a sunny afternoon the column and statue together cast a shadow 30 m long. At the same moment, a 6 m flagpole nearby casts a shadow of 9 m. The ground is flat and both stand upright.
How tall is the statue itself?
Challenge
The column GM is 6 m and the statue MT stands on it. Their shadow GS is 30 m. The flagpole RQ is 6 m with a 9 m shadow RU. Find the statue's height MT, then press Check.
