two angels are vertical angles. One angle is labeled 2x. the other angle is labeled (x+30). Find the value of x.

x=30

Step-by-step explanation:

2x=x+30

x=30

check the picture below.

well, the angle at the vertex d is clearly not a right-angle, let's check for the one at the vertex f which does look like,   however if it's indeed, that means ef is perpendicular to df, in which case their slopes will be negative reciprocal of each other.

so the negative reciprocal of the slope of ef is 1, however the slope of df is not 1, is 1/2, so nope, they're not perpendicular lines.

i think it would be c
