The angle subtended by a coin of radius 1 cm held at a distance of 80c

1.	The angle subtended by a coin of radius 1 cm held at a distance of 80cm from your eyes is :
Answer» 1.25 rad 0.125 rad `0.0125^(@)` `0.025^(@)` Solution :`"ANGLE "THETA=(B)/(x)` `x=80xx10^(-2)` `b=1 cm=1xx10^(-2)m` `THEREFORE theta=(1xx10^(-2))/(80xx10^(-2))=(1)/(80)=0.125" rad"`
