Step-by-step explanation:
Answer:
123 degrees
Step-by-step explanation:
Well, since we have a 4 sided figure, we know that the sum of the interior angles is 360 degrees.
(n-2)*180=(4-2)8180=360
Okay we are given 3 angles
120+43+74= 237
that means that x= 360-237
x=123 degrees
A. x = -6
6-x-x = 18
6-2x =18
-2x = 12
x = -6
