Determine the angle of elevation of the top of the building from A.

      

A man walks directly from point A towards the foot of a tall building 240 m away. After covering 180 m, he observes that the angle of elevation of the building is 45o. Determine the angle of elevation of the top of the building from A.

  

Answers


John
tan 45o = $\frac{h}{60}$

h = 60 tan 45o

h = 60 x 1 = 60 m

tan $\theta$ = $\frac{60}{240}$ = 0.25

therefore $\theta$ = 14. 04
