<h2>question :</h2>
40. which of the following equation graphs as a vertical parallel to the y-axis?
41. if ΔABC = ΔFGH, then which of the following statements is not necessarily true?
<h2>my answer :</h2>40. the meaning of "vertical parallel to the y-axis" is a line that is perpendicular to the x-axis
then the equation that can be written parallel to the line y is x = a, a is the distance from point 0.
(*the second choice is correct)
41. if ΔABC = ΔFGH, it can be said that the second triangle of the shape is congruous (*in the picture)
(*the second choice is correct)
The length of AE is
Explanation:
From the figure, we can see that the two triangles ΔAED and ΔACB are similar. Thus, the legs of the triangle are proportional to each other.
Thus, we have,
Substituting the values of the sides from the image, we get,
Multiplying both sides of the equation by 6, we get,
Multiplying, we have,
Thus, the length of AE is
