To Whom it May Concern, I'm trying to get this code working. Here's my question: Consider a triangle with sides of length 3, 7, and 9. The law of cosines states that given three sides of a triangle (a, b, and c) and angle C between sides a and b: Write Python code to calculate the three angles in the triangle. Here's my code: # Calculate the angles in a triangle # Imports the Math data import math # Sets up the different angles with corresponding letters # The first angle is a a = 3 # The second angle is b b = 7 # The third angle is c c = 9 # Calculates angle "C" print(math.acos(((a**2)+(b**2)-(c**2))/(2(a*b)))) Here's my output: Traceback (most recent call last): File "E:\Programming\Problem4.py", line 12, in <module> print(math.acos(((a**2)+(b**2)-(c**2))/(2(a*b)))) TypeError: 'int' object is not callable
