Given an angle measure in radians, we can convert it to degree by multiplying the angle in radians with
[tex]\theta\cdot\frac{180°}{\pi}[/tex]Part A:
[tex]\begin{gathered} \frac{7\pi}{4}\cdot\frac{180°}{\pi}=\frac{7\cdot180°}{4} \\ =315° \\ \\ \text{Therefore, }\frac{7π}{4}\text{ is }315°. \end{gathered}[/tex]Part B:
[tex]\begin{gathered} \frac{5π}{3}\cdot\frac{180°}{\pi}=\frac{5\cdot180°}{3} \\ =300° \\ \\ \text{Therefore, }\frac{5\pi}{3}\text{ is 300\degree.} \end{gathered}[/tex]
