Question

If $AB\parallel CD,$ then find the value of x and y

Answer 1

Consider given the figure,

Line, $AB\parallel CD$ and line P is transversal line.

Now. $x+\angle {105}^0=\angle {180}^0$ ( angle x and angle${105}^0$ are supplementary angle)

$x=\angle 180-\angle {105}^0={75}^0$

Now, $\angle y=\angle x$ (alternate interior angle)

$\angle y={75}^0$

Hence, this is the answer.
