19. The measures of the three angles of a triangle are given by x + 4, x, and 2x.
What is the value of x?

numbers

Step-by-step explanation:

a .4y4

hope this !

c

step-by-step explanation:

there is vertical asymptote at x = 2 and x = 0

vertical asymptote occurs at the points where the denominator is 0. so we can say that

x = 2 occurs when there is a factor (x-2) in the denominator, and

x = 0 occurs when there is a factor "x" in the denominator

thus, the denominator of the equation would have "x * (x-2)", this is option c only. that's the correct answer.
