Brad places a marker on the ground 10 ft. away from the base of a tree at a botanical garden. He walks back towards the tree until he is standing 4 ft. away from the marker, and he is 6 ft. tall. Assuming that the top of Brad's head, the top of the tree, and the marker form two simliar triangles, how tall is the tree

Answer:

15ft

Step-by-step explanation:

Calculation for how tall is the tree

First step Let the proportion be x/10ft = 6ft /4ft

Second step is to cross-multiply by 4x

4x =10ft*6ft

4x = 60

Third step is to divide both sides by 4

4x = 60

4x/4=60/4

x=15 ft

Therefore the tree will be 15ft tall
