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.

Answer:
(-3a+-2x)(2a+-1x)=0
Step-by-step explanation:
Simplifying
x2 + -1ax + -6a2 = 0
Reorder the terms:
-1ax + -6a2 + x2 = 0
Solving
-1ax + -6a2 + x2 = 0
Solving for variable 'a'.
Factor a trinomial.
(-2a + -1x)(3a + -1x) = 0
