Textbook Problem

*In Exercises 17 to 22, use proportions to solve each problem.*

Assume that *AD* is the geometric mean of *BD* and *DC* in

a) | Find AD if BD = 6 and DC = 8. |

b) | Find BD if AD = 6 and DC = 8. |

To determine

**a)**

**To Find:**

The value of *AD*.

Explanation

If *b* is the geometric mean of *a* and *c*, then

**Calculation:**

It is given that *AD* is the geometric mean of *BD* and *DC.*

Use the concept of geometric mean.

Substitute *BD* = 6 and *DC* = 8 in

To determine

**b)**

**To Find:**

The value of *BD*.
