When laser light of wavelength 632.8 nm passes through a diffraction grating, the first bright spots occur

Question:

When laser light of wavelength 632.8 nm passes through a diffraction grating, the first bright spots occur at ±17.8° from the central maximum.

(a) What is the line density (in lines cm) of this grating?

(b) How many additional bright spots are there beyond the first bright spots, and at what angles do they occur?
