From figure l∥m, and ‘P’ is transversal, then x+y+z=

$2 x ° = 70 ° (∴ corresponding angles are equal)$

$x ° = 35 °$

$2 x + y = 180 °$ $(∴ linear pair)$

$70 + y = 180 °$

$y = 110$

$∴$ $y = z = 110 °$ $(∴ corresponding angles are equal)$

$∴$ $x + y + z = 35 ° + 110 ° + 110 ° = 255 °$

From figure $l ∥ m,$ and $‘ P ’$ is transversal, then $x + y + z =$
