B.) 60°

C.) 85°

D.) 95°

E.) 105°

∠AXZ is 130°, therefore

∠ YXZ is 50° {angles on a straight line add up to 180°}

Angles in a triangle add up to 180°

180 - (45 + 50) = ∠XZY {subtracted the known angles from 180 to find the missing angle}

180 - 95 = ∠XZY {added in parentheses}

85° = ∠XZY {subtracted}

**C.) 85°**
