Answer 1

Answer:

The height of the palm tree will be 15m.

1. Firstly make two straight lines DE and AB
2. DE must be the smaller one and AB must be the bigger one that is DE is the boy standing and AB is the palm tree.
3. Join EB and AD.
4. Make DC perpendicular to AB.
5. In rectangle BEDC, DE=BC=1.8cm and DC=BE=13.2cm.
6. The angle of elevation of the top off the tree from his eyes is 45 degree that is angle ADC is 45 degree.
7. In triangle ADC , AC/DC= tan 45

• AC/13.2=1
• AC=13.2cm 8. So, AB= AC + BC
• AB=( 13.2 + 1.8)m
• AB=15m
