Question

question 8 (multiple choice worth 1 points) (01.06r mc) if d is the midpoint of $overline{ab}$ and ab = 15, what is ad? 7.5 15 22.5 30 question 9 (multiple choice worth 1 points) (01.06r lc) what is a requirement of adjacent angles? adjacent angles must be vertical

Explanation:

Step1: Recall mid - point property

The mid - point of a line segment divides the line segment into two equal parts. So, if D is the mid - point of $\overline{AB}$, then $AD=\frac{1}{2}AB$.

Step2: Substitute the value of AB

Given $AB = 15$, substituting into the formula $AD=\frac{1}{2}AB$, we get $AD=\frac{1}{2}\times15 = 7.5$.

Answer:

7.5
