Observer 64354

At what angle of view does an object 70 m long appear to the observer, 50 m away from one end and 80 m from the other end?

Correct answer:

γ =  60 °

Step-by-step explanation:

c=70 m a=50 m b=80 m  c2=a2+b22 a b cosγ  γ1=arccos(2 a ba2+b2c2)=arccos(2 50 80502+802702)1.0472 rad  γ=γ1  °=γ1 π180   °=1.0472 π180   °=60  °=60
