Question

pls refer to the attachment and answers​

Answer 1

Answer:

Values of all angles are 80° here

Answer 2

Answer:

We know

L parallel to M

then

angle z= angle t(corresponding angles)

angle z=80° (vertically opposite angles)

thus angle t=80°

also

angle y=angle x(corresponding angles)

We've P parallel to Q

angle y=80° (alternate interior angles)

angle x=angle y=80°

hope it helps
