Answer:
x = 64°
Explanation:
Since the triangle is isosceles, the base angles are congruent, that is
∠ R = ∠ Q = 32° , then
vertex angle = 180° - (32 + 32)° = 180° - 64° = 116°
∠ NSR = 116° ( vertically opposite angle )
∠ MNS and ∠ NSR are same- side interior angles and sum to 180° , then
x = 180° - 116° = 64°
