Answer:
Option C =11.4 units.
Explanation:
We are given that O is the center of the given circle and chord GH and HJ are congruent.
We have find the measure of chord of HJ.
We are given that measure of GH in the given figure
Measure of chord GH=11.4 units
Congruent sides: When two sides are congruent then the two sides have same length .
We are given that
By definition of congruent sides
Measure of GH= Measure of HJ
Measure of HJ=11.4 units
Hence, the measure of chord HJ=11.4 units .Therefore, the option C is correct option.
