Cindy is 72 inches long. Imagine it like a right triangle. Her shadow is the base, she is the side, and the distance between her head and the end of the shadow is the diagonal line connecting the two. Use the Pythagorean theorem to find how tall cindy is.
a²+b²=c² a=21, the length of the shadow b= ? cindy's height c= 75, the distance from her head to the edge of the shadow 21²+ b²=75² 441 +b² = 5625 -441 -441 ------ ------- 0 5184 b² = 5184 √b² =√5184 b= 72
