Answer:
x = z = 70°
y = 110°
Explanation:
From the diagram, we have 4 angles;
To find y;
110° and y are vertically opposite angles so they are equal.
So, y = 110°
Also, y and x lie on a straight line. Sum of angles on a straight line is 180°;
y + x = 180
110 + x = 180
x = 180-110 = 70°
Also, x and z are vertically opposite angles and they are equal;
x = z = 70°
y = 110°
