Answer:
∠ X = 80° , ∠ V = 60°
Explanation:
(a)
Since XY and WX are congruent then the triangle is isosceles and the 2 base angles are congruent, that is
∠ W = ∠ Y = 50° , so
∠ X = 180° - (50 + 50)° ← sum of angles in triangle
∠ X = 180° - 100° = 80°
(b)
Since the 3 sides are congruent then the triangle is equilateral with the 3 angles congruent, each 60°
∠ V = 60°
