Question

If there is building having height 9m.An observer observing at 60° angle of eleva tion.what will distance between building and observer

Answer 1

Answer:

3√3 m

Step-by-step explanation:

building height=9 m

let the distance between observer and building be x mtr.

therefore, 9/x=tan 60°=√3

therefore,9/√3=x

so,x=3√3m

hence, the distance between observer and building is 3√3m✓✓
