Question 302186
Julia, who is 1.51 m tall, wishes to find the height of a tree with a shadow 31.05 m long. She walks 20.70 m from the base of the tree along the shadow of the tree until her head is in a position where the tip of her shadow exactly overlaps the end of the tree top's shadow. How tall is the tree? Round to the nearest hundredth. 
------------------------
Draw the picture.
---
Ht of tree/length of shadow = height of Julia/shadow of Julia
----------------------------
T/31.05 = 1.51/(31.05-20.7)
---
T/31.05 = 1.51/10.35
---
T = 4.53 m
