Question

In figure if l parallel to m , then x = ?

Answer 1

Step-by-step explanation:

${\qquad \underline{\sf \bold {Step-by-step \: ex planation:}}}$

:. 30 + 40 + y = 180 --------------------------------------(let's take the third angle as y)

(because of angle sum property of triangle)

70 + y = 180

y = 110

therefore angle LOX = Angle Y

:. Angle LOX = 110

as L ll m

110 + x = 180 ----------------------(co interior angles)

:. x = 180 - 110 = 70

hence solved!!!!
