# AC and DB are chords that intersect at point H.

Students were asked over to answer a question at schools and to express what is most important for them to succeed. Of the many comments, one that that stood out was practice. People who usually are successful do not become successful by being born. They work hard and perseverance their lives to succeeding. If you would like to reach your goals, keep this in mind! down below are one of the answer and question example that you would probably benefit from to practice and expand your practical knowledge and also give you insights that could just help you to preserve your study in school.

## Question:

AC and DB are chords that intersect at point H.What is the length of line segment DB?
4 units
8 units
16 units
20 units

16 units

Step-by-step explanation:

see the attached figure to better understand the problem

Applying  the Intersecting Chords Theorem

we have that

substitute the given values

Simplify

Find out the length of segment DB

Note In this problem it was not necessary to determine the value of x to calculate the DB segment.

Anyway, the calculation was done for didactic purposes.

From the answer and question examples above, hopefully, they might be able to assist the student answer the question they had been looking for and observe of every single thing declared in the answer above. You will possibly then have a discussion with your classmate and continue the school learning by studying the question alongside one another.
