Question

110° х z у Find the unknown angle measures

Answer 1

Answer:

     x  = z  = 70°

        y = 110°

Step-by-step 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°
