sweet-ann [11.9K]

Answer:

the tree is 8.8 m tall

I can't draw it but it will be two similar acute triangles. The one that represents the man will have a 2m height and a 5m base. The one that represents the tree will have an 8.8m height and a 22 m base.

Step-by-step explanation:

it's a proportional relationship

5/22=2/height

5(height)=2(22)

5(height)=44

divide both sides by 5

5(height)/5=44/5

height=8.8 m
