Text Solution

AI Generated Solution

To solve the problem step by step, we need to find the value of \( \angle B - \angle C \) in triangle \( ABC \) where \( \angle A = 60^\circ \) and the ratio \( b : c = (\sqrt{3} + 1) : 2 \). ### Step 1: Set up the known values We know: - \( \angle A = 60^\circ \) - The ratio \( b : c = \sqrt{3} + 1 : 2 \) Let \( b = k(\sqrt{3} + 1) \) and \( c = 2k \) for some positive constant \( k \). ...
