a] 0,45 radian

[tex]0.45^{c} = 0.45 \times \frac{180}{\pi} \\ {0.45}^{c} = 0.45 \times \frac{180}{3.14} \\ {0.45}^{c} = \frac{81}{3.14} \\ {0.45}^{c} = 25.8 ^{0} [/tex]

b] 0,89 radian
[tex]0.89^{c} = 0.89 \times \frac{180}{\pi} \\ {0.89}^{c} = 0.89 \times \frac{180}{3.14} \\ {0.89}^{c} = \frac{160.2}{3.14} \\ {0.89}^{c} = {51}^{0} [/tex]
