Final answer:
The two bottom angles plus the top angle in a triangle always add up to 180 degrees. The value of one of the bottom angles cannot be determined solely from the given information.
Step-by-step explanation:
In a triangle, the sum of all three angles is always 180 degrees. Therefore, if we have two bottom angles and a top angle, their sum will also be 180 degrees.
If we let one of the bottom angles be x degrees, then the other bottom angle will also be x degrees because the two angles are equal in measure.
So, we can set up the equation: x + x + top angle = 180 degrees.
Since the top angle is not given, we cannot determine the exact value of one of the bottom angles. The answer could be any angle smaller than 180 degrees.
Therefore, the correct answer is (C) 60 degrees.
