Ruth decides to use the method of proportions and similar triangles to find the height of a tree. She measures the length of the tree's shadow and finds it is 12 feet long. Then she holds a 12-inch ruler perpendicular to the ground and finds that it casts a 6-inch shadow. How tall is the tree? a. 2 ft c. 24 ft b. 6 ft d. 144 ft

c. 24 ft

Step-by-step explanation:

if the 12 inch ruler casts a 6 inch shadow (shadow has half size) then a tree with 12 feet long shadow will have a height of 24 feet
