In a circle, two chords that are equidistant from the center of the circle are always ? *

perpendicular
None of these
equal in length
bisectors of one another

option C.

Step-by-step explanation:

According to equidistant chords theorem, two chords of a circle are congruent if and only if they are equidistant from the center of the circle.

Congruent means they are equal in length.

Using equidistant chords theorem, we can fill the blank.

In a circle, two chords that are equidistant from the center of the circle are always equal in length.

Therefore, the correct option is C.

15%

step-by-step explanation:

use the table and count the number of guesses that has two correct answers.

the following are two correct answers

10010, 01100, 11000

a total of 3 numbers having 2 correct guesses out of 20 questions.

probability of getting 2 correct guesses = the number of questions getting 2 correct answers / total number of questions.

= 3/20

to convert it into percent multiply by 100, we get

= 3/20 * 100

= 15%

the answer is 15%

you.

8

step-by-step explanation:

just put √(2) * √(32) into a calculator. that will make the answer be 8.
