There are three answers and they are: choice 2, choice 3, choice 5
======================================================
Further Explanation:
Choice 1 is false because the intersection of the altitudes of a triangle leads to the orthocenter.
----
Choice 2 is true because the three medians of any triangle always intersect at the centroid. A median is a line that goes from one vertex to the midpoint of the opposite side. In this case, we go from point E to the midpoint of side CD. The midpoint of CD is found by bisecting segment CD (see choice 5)
----
Choice 3 is true. This is effectively the same as choice 5 below. The "perpendicular" aspect does not matter.
----
Choice 4 is false. Following the steps mentioned here will create an altitude line (see choice 1)
----
Choice 5 is true. To bisect something is to cut it in half. Let's say that point F is the midpoint of line segment CD. This means that line segment EF is one of the three medians of triangle CDE.

edit update: I changed choice 3 from false to true
Answer:
can u send a lic of the acc question
Just set up a proportion with the original numbers and then the numbers you want to find like so: (x1/y1)=(x2/y2) and since you want to find the second y value, just leave y as a variable like so: (15/24)=(3/y) after this just cross multiply and get the answer: 15y=72.....y=4.8
Tn = a + (n-1)d
when n = 12, tn = 63
63 = a + (12-1)*5
a = 63 - 55 =8
tn or an
= 8 + (n-1) 5
= 3 + 5n
Hope this helps
