Answer 1

Answer:

72 degrees.

Step-by-step explanation:

The angle marked as 72 degrees and the angle of JOK are considered vertically opposite angles in relation to each other. This relationship means that the angles are equal.

Answer 2

$\boxed{Option \ C}$

Step-by-step explanation:

Congruent arcs subtend congruent central angles.

So,

∠GOH ≅ ∠JOK

∠JOK = 72 degrees
