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)
