Answer:

The tree is 45 meters high.

Step-by-step explanation:

Drawing this out will make it much easier.

In the figure, 3 is proportional to 27, and 5 is proportional to the missing side (x).

Insert the figures into an equation and solve:

3/5 * 27/x

Cross multiply:

3(x)= 27(5)

3x=135

135/3=x

x=45
