Pls explain this
In a parallelogram opposite sides are equal so in CLUE , L = E i.e E = 70o
In a parallelogram adjacent sides are supplementary i.e add up to 180. So , In RISK , K + S = 180
120 + S = 180
S = 180 - 120
S = 60o
Then mark the intersection of side IS and CE as O , whose angle is x.
Then we get a triangle SOE , in which S = 60 and E = 70
Now , we can use angle sum property of triangle .
Interior angles in a triangle add up to 180.
S + E + x = 180
60 + 70 + x = 180
130 + x = 180
x = 180 - 130
x = 50o
