1(a) Pie chart for export values

Total export value = $100 + 240 = 340$ units.

Sector angle formula: $\theta = \dfrac{\text{value}}{\text{total}} \times 360^\circ$

For Fiber co.:

$$\theta = \dfrac{100}{340} \times 360^\circ$$

Simplify fraction: $\dfrac{100 \div 20}{340 \div 20} = \dfrac{5}{17}$

$$\theta = \dfrac{5}{17} \times 360^\circ = \dfrac{1800}{17}^\circ \approx 105.88^\circ$$

For Timber co.:

$$\theta = \dfrac{240}{340} \times 360^\circ$$

Simplify fraction: $\dfrac{240 \div 20}{340 \div 20} = \dfrac{12}{17}$

\theta = \dfrac{
