Question

I don’t get it ?? could someone work through it so I can understand how you get to the answer, thanks

Answer 1

the answer would be 60 if im corrected

Answer 2

if sum of the angle measures total 360, you see in the diagram that adding all of thme up should get you 360

2a + a + 2a + a = 360

6a = 360

a = 60

the angles are 60, 60, 120, 120
