Find the value of x. The dot represents the center of the circle, 20 represents the length of the diameter, and 16 is the length of the chord.
picture is attached

x = 6

Step-by-step explanation:

Looking at the attached figure:

As the triangle ABC is inscribed inside the circle and AB is the diameter of the circle => ABC is the right triangle

So that ∡ACB = 90°

As ACB is the right triangle, according to the Pythagoras theorem, we have the formula as following:

=>

=> BC = 12

As O is the center of the circle

=> OA = 1/2 x AB = 1/2 x 20 = 10

Inside the triangle ABC, as OD is parallel with BC

=> AOD and ABC are similar triangles

=>

=>

=> x = 1/2 x 12 = 6

So x = 6

1/4 and 8/3 because:

the reciprocal if 4 is 1/4 because 4 is used as 4/1 and the opposite of that is 1/4. the opposite of 3/8 is 8/3 so that is the answer.

6, 10

9, -13

12, -21

18, -23

step-by-step explanation:

you just add 6 to the x-coordinate and subtract 10 from the y-coordinate.
