Answer
a). $105^{\circ}=105\times\frac{pi}{180} rad=1.83 rad$
Also, $105^{\circ}=\frac{105}{360}rev=0.29rev$
b). $1.8rad=1.8\times\frac{180}{pi}=103^{\circ}$
Also, $1.8rad=103^{\circ}=\frac{103}{360}rev=0.29rev$
c). $\frac{5}{7}rev=\frac{5}{7}\times360^{\circ}=257^{\circ}$
Also,$=257\times\frac{pi}{180}=4.49rad$
