Answer: THIRD OPTION.
Step-by-step explanation:
Given the trapezoid in the figure, you know the coordinates of two points:
(0,c) and (a,b)
You can observe that the point (a,b) and the point P have the same x-coordinate, because both points are "a" units from the origin.
Then, the x-coordinate of P is:
[tex]x=a[/tex]
Now, in order to find the y-coordinate of the point P, you need to remember that when the line touches the x-axis, the value of "y" is equal to zero. Therefore, the y-coordinates of the point P is:
[tex]y=0[/tex]
Then the answer is:
[tex](a,0)[/tex]
