Question

find the lettered angle in each case ​

Answer 1

Answer:

Angle z=70 degree Angle y=110 degree and x=70 degree

Step-by-step explanation:

Angle z+ 110 degree = 180 deg. (Linear pair of angles)

Angle z = 180 deg. - 110 deg.

Angle z= 70 deg.....

And

Angle x=70 degree(Vertically opposite angles) and

lastly we have to find Angle y

That's--------------

Angle y+ Angle x=180 degree ( Co-interior angles)

So that angle y+70 deg. = 180 deg

Angle y = 180 - 70 deg

Angle y= 110 degree

Plz mark me brainliest and also tell from which class did it belongs to???
