The formula to calculate the number of images formed,

\(Number\ of\ images\ formed\ =\ \frac{360°}{Angle\ of\ inclination}\ +\ 1\)
\(Number\ of\ images\ formed\ =\ \frac{360°}{Angle\ of\ inclination}\)
\(Number\ of\ images\ formed\ =\ \frac{360°}{Angle\ of\ inclination}\ -\ 1\)

Substitute the values,

\(Number\ of\ images\ formed\ =\)
