Question

If d is the midpoint of segment ab and ab = 15, what is ad? A. 7.5 B. 15 C.22.5 D.30

Answer 1

If d is the midpoint of segment AB and AB = 15, then the length of AD is half of the length of AB because the midpoint divides the segment into two equal parts.

So, AD = AB / 2
AD = 15 / 2
AD = 7.5

Therefore, AD is 7.5 units long.

The correct answer is A. 7.5
