_______________ is the sum of an exterior angle and its adjacent interior angle

1

(a)

Straight angle

In a quadrilateral MORE, if \(\angle\)M = 120°, \(\angle\)R = 30° and \(\angle\)O= 150°, then \(\angle\)E =__________________

1

(a)

\(\because \angle M+\angle R+\angle O+\angle E=360°\)
\(\Rightarrow120°+30°+150°+\angle E=360°\Rightarrow 300°+\angle E=360°\)
\(\therefore\angle E=360°-300°=60°\)
