Problem
In circle \( X, \mathrm{~m} \angle V W U=43^{\circ} \). Solve for \( x \) if \( \mathrm{m} V U=(7 x+46)^{\circ} \). If necessary, round your answer to the nearest tenth.
Solution
Step 1 ：\( \mathrm{m} \angle VWU = 43^{\circ} \)
Step 2 ：\( \mathrm{m}VU = (7x+46)^{\circ} \)
Step 3 ：\( 43^{\circ} = \frac{1}{2} (7x+46)^{\circ} \)
