Answer:
In ||gm RISK,
KR || SI and KS is transversal
= Angle K + Angle S = 180°. (interior angles)
= Angle S = 180-150
= 30°
In ||gm CLUE,
Angle L = Angle E.(opposite angles of a ||gm are equal)
=Angle E = 70°
Angle E =70° and Angle S = 50°
therefore x = 180-(70+50)
=180-120
=60°.
(by angle sum property) and (vertically opposite angles property)
