How to find the measure of a missing angle

79°

Step-by-step explanation:

Sum of all angles in a quadrilateral is always 360°.

So,

B+C+D+E=360

80+100+101+E=360

281+E=360

E=360-281

E=79

Hope this will help:-)

after going and makeing graphs i would go with a,

there is nothing that is matches the graph. if there was i would show you. but therefore my answer is a.

hope i
