Question

In each of the following figures, arrows are marked
to show the parallel lines. Find the values of x, y and z
in each case​

Answer 1

Answer:

1. x=50° (vertically opposite angles)

y=50° (alternate interior angles)

z= 180-50 = 130° (linear pair)

2. z=125° (vertically opp)

x=125° (corresponding angles)

y= 180-125 = 55° (linear pair)

3. y=70° (alt. int. angles)

z=x= 180 - 70 = 110° (linear pair)

4. y=120° (corresponding angles)

x=z= 180-120= 60° (linear pair)
