Given o [theta] below if gh and hj are congruent what is the measure of chord hj?

ok if GH line length is that 8.6 you do the following:

since OH and OG are radiuses they are equal, we have in the triangle two equal angles beside 82 means each angle is 49 degree, now use "sine law" sine 82 / GH (8.6) = sine 49 / OH, OH equal 6.55, this is the radius, theta = arc/radius, provided that theta is in radian, 82 degree in radians would be 1.43 something multiply that by 6.55 (radius) you get arc GH = 9.4, since GH and HJ arcs are congruent hj = 9.4, if the answer is wrong tell me to revise in case you have a guide answre

step-by-step explanation:

when rotating a figure 180 degrees, imagine that you are able to take the figure and turn it clockwise or counterclockwise around a center point. to rotate a figure 180 degrees, you will need to apply the rule (x, y) → (-x, -y). start by using a coordinate grid with coordinates for each vertex of the figure. the center point of the coordinate grid is located at (0, 0), which is what you will rotate the figure around. write down the original coordinates of the shape you are going to rotate. then, apply the rule. for example, coordinate (1, 2) becomes (-1, -2). another example would be, coordinate (-4, -2) becoming (4, 2). after you change each original coordinate to the rotated coordinate, you will draw your new figure.
