A) \[\,{{\text{ }\!\!\theta\!\!\text{ }}_{i}}+{{\text{ }\!\!\theta\!\!\text{ }}_{c}}={{\text{ }\!\!\theta\!\!\text{ }}_{n}}\]
B) \[\,{{\text{ }\!\!\theta\!\!\text{ }}_{i}}\text{-}{{\text{ }\!\!\theta\!\!\text{ }}_{c}}=2{{\text{ }\!\!\theta\!\!\text{ }}_{n}}\]
C) \[\,\frac{{{\text{ }\!\!\theta\!\!\text{ }}_{i}}\text{+}\,{{\text{ }\!\!\theta\!\!\text{ }}_{c}}}{2}={{\text{ }\!\!\theta\!\!\text{ }}_{n}}\]
D) \[\,{{\text{ }\!\!\theta\!\!\text{ }}_{c}}\text{-}{{\text{ }\!\!\theta\!\!\text{ }}_{i}}=2{{\text{ }\!\!\theta\!\!\text{ }}_{n}}\]
Correct Answer: C
Solution :
\[{{\theta }_{n}}-{{\theta }_{c}}={{\theta }_{i}}-{{\theta }_{n}}\] or \[{{\theta }_{n}}=\frac{{{\theta }_{i}}+{{\theta }_{c}}}{2}\]You need to login to perform this action.
