Answer:
An open circuit is one where the continuity has been broken by an interruption in the path for current to flow. A closed circuit is one that is complete, with good continuity throughout.
Explanation:
For instance, a simple light switch opens and closes the circuit that connects a light to a power source. When you build a circuit, it's a good idea to disconnect the battery or other power source when the circuit is not in use.

Answer:
136°
Explanation:
Theorem: The measure of the angle formed by a tangent and a chord is equal to one-half the measure of the intercepted arc.
In the diagram below, PR is the chord, PRS is the tangent, and PQR is the intercepted arc.
Per the theorem,
mPRS = ½mPQR
mPQR = 2mPRS = 2 × 68° = 136°
The measure of the intersected arc is 136°.
