Answer:

6.93 meters

Step-by-step explanation:

Use similar triangles to solve

if the tree shadow is 26.05m  long and she stands 20.6 meters away from the tree, so her shadow meets the tip, her shadow is 26.05-20.6 = 5.45

height of Emily divided by the shadow of Emily must equal the height of the tree divided by the shadow of the Tree

1.45 /5.45=x/26.05

26.05 x (1.45/4.45)=x

x= 6.93
