Problem
If the central angle whose measure \( 110^{\circ} \), then the measure of the tangent angle which subtended to the same arc equals .....
Solution
Step 1 ：\( \text{Central angle} = 110^{\circ} \)
Step 2 ：\( \text{Tangent angle} = \frac{1}{2} \times \text{Central angle} \)
Step 3 ：\( \text{Tangent angle} = \frac{1}{2} \times 110^{\circ} \)
