Answer:
x = 91°
Step-by-step explanation:
The figure has 10 angles, so their sum will be (10 -2)180° = 1440°.
Working clockwise from left, we have ...
x + 98 +127 +330 +120 +92 +120 +90 +(360 -68) +80 = 1440
x = 91 . . . . . . . subtract 1349 from both sides
The value of the missing angle is 91 degrees.
