Question
What is the temporary assumption used to prove that “If a + b ≠ 18, and a = 16 then b ≠ 2”?
- b > 2
- b < 2
- b ≥ 2
- b = 2
The correct answer is: b = 2
We first assume b = 2
And we prove it as a contradiction

If G is the centroid of triangle ABC,
Find CG
>>>CG was given as 5x+1 and CF can be found in terms of x.
>>>There is no scope to find the value of x.
>>>Hence, we have no way to find the value of CG.
