12. Find the measure of and if in Fig 3.34.
(If you find , is there more than one method to find ?)
Given,
(angles on same side of transversal)
(angles on same side of transversal)
Yes, to find there is more than one method.
PQRS is quadrilateral so sum of all angles is 360
and we know
so put valuse of and we get measurement of
