Question

What is the measure of JOK, given that GH=JK ?

A.
288

B.
108

C.
72

D.
18

Answer 1

72 degrees.

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}`

Explanation:

Congruent arcs subtend congruent central angles.

So,

∠GOH ≅ ∠JOK

∠JOK = 72 degrees
