Find the value of x.
answer options: 4, 6, 5, 7

x = 6

Step-by-step explanation:

The radius in this case measures; 20/2 = 10 since the diameter is 20.

The chord measuring 16 units has been bisected, hence each portion measures 8 units.

We now apply Pythagoras theorem since we are dealing with a right angled triangle with 2 given sides;

x^2 = 10^2 - 8^2

x^2 = 36

x = 6

the answer is (-8,-5)

step-by-step explanation:

the endpoint to midpoint is half the length. the length is (-2,-1) so when you are at the midpoint just add it to it to find your answer -6+(-2)= -8 and -4+(-1)=-5 so (-8,-5)
