Syntax error

Question

My program says theres an error in side_a, i cant distinguish help me

import math

#input user

side_b = float(input("Enter value for side b:"))
side_c = float(input("Enter value for side c:"))
angle_A = math.radians(int(input("Enter value for angle A:"))

#declare variable for computations

side_a = math.sqrt(side_b*side_b + side_c*side_c - 2 * side_b * side_c * math.cos(angle_A))
angle_B = math.asin(side_b * math.sin(angle_A)/side_a)
angle_C = math.asin(side_c * math.sin(angle_A)/side_a)
s = (side_a+side_b+side_c)/2
Area = math.sqrt(s*(s-side_a)*(s-side_b)*(s-side_c))
MedianM = (1/2)*math.sqrt(2*(side_a*side_a) + 2*(side_c*side_c) - (side_b*side_b))
MedianN = (1/2)*math.sqrt(2*(side_b*side_b) + 2*(side_c*side_c) - (side_a*side_a))
MedianP = (1/2)*math.sqrt(2*(side_a*side_a) + 2*(side_b*side_b) - (side_c*side_c))

print("The value of side a is:", side_a)
print("The value of angle B is:", angle_B)
print("The value of angle C is:", angle_C)
print("The total area of the triangle is:", Area)
print("The length of median M is:", MedianM)
print("The length of median N is:", MedianN)
print("The length of median P is:", MedianP)

Answer 1

Do a paranthesis count for each line...

Edit.
the line before, the one with angleA is missing a )
