Answer: B, x=20; angle measure is 30°.
Step-by-step explanation:
Opposite angles are always the same.
You can see that 30° and 3x are opposite angles therefore 3x=30°.
In algebra, when a letter and a number are next to each other, it means times.
So, 3x=30° means 3 times something equals 30.
And we know that 3×10=30 so, x=10.
Hope this helps :)

Answer:
32.72 degrees
Step-by-step explanation:
This is an 11-gon
the sum of INTERIOR angles is (11-2) 180 = 1620
so each interior angle = 1620 / 11 = 147.2727
angle 1 is 180 - 147.2727 = 32.72 degrees
