Solution:
we are given that
The center camera directly faces the news anchor's desk. it mean it is at an angle of 0 degree with the anchor face.
Each camera has a field of 60°.
It mean 30 degrees on either side.
Second camera is 45 degree away and aslo it the angle of coverage of 30 degree on either side will become 15 degree to 75 degree.
Third camera is 45 degree away on another side and aslo it the angle of coverage of 30 degree on either side will become -15 degree to -75 degree.
So total coveregae by all the three camers
