Ruth decides to test the method of proportions and similar triangles to find the height of a tree. She decides to again find the
height of a tree she had measured earlier in the day at 10 A. M. This
time, she decides to use this method at 5 P. M. in the evening. She
measures the length of the tree's shadow and finds it to be 48 feet
long this time. Then she holds a 12-inch ruler perpendicular to the
ground and finds that it casts a 24-inch shadow. How tall will she find
the tree?
a. 6 ft c. 48 ft
b. 24 ft d. 288 ft
