Question

In the above figure both RISK and CLUE are parellelograms . Find the value of x

Answer 1

Answer

x = 50°

How did I get it:

∠UEC = 70° (Opposite angle are equal)

120° + ∠KSI = 180°

∠KSI = 180 - 120

∠KSI = 60°

Consider △EOS,

∠UEC + ∠KSI + ∠EOS = 180° (angle sum property)

70° + 60° + ∠x = 180

130 +∠x = 180

∠x = 180 - 130

∠x = 50°
