Calculate the angle subtend by the man

Reference no: EM13667153

A large man stands 1kilometer away.

a) Calculate the angle subtend by the man? (radians)

b) If you view the man through a telescope with f0=50 centimeter and fe = 2.5 centimeter, calculate the subtended angle of the image. Compare this with the angle subtended by your thumb when you hold it at arm's length.
