Horizontally 6296

The camera with a viewing angle of 120 ° was placed horizontally on the observatory at 30 m. What length d of the section at the tower's base can the camera not capture?

Correct answer:

d =  17.3205 m

Step-by-step explanation:

h=30 m A=120   B=A/2=120/2=60    tan B = h:d  d=h/tanB=h/tan60° =30/tan60° =30/1.732051=17.321=17.3205 m
