Answer:
A
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°, thus
x = 180° - (52 + 32)° = 180° - 84° = 96°
The external angle of a triangle is equal to the sum of the 2 opposite interior angles.
y is an exterior angle of the triangle, thus
y = 52° + 32° = 84°
z = 180° - (55 + 84)° = 180° - 139° = 41°
In conclusion
x = 96°, y = 84° and z = 41°
