Answer:
x=3
Step-by-step explanation:
All the angles added together must equal 360 degrees.
74+43+50+37+12x+12x+11x+17x = 360
Simplify the equation by adding like numbers.
204+52x=360
Subtract 204 from both sides of the equation.
204+52x-204=360-204
52x=156
Now, divide both sides by 52.
52x/52=156/52
x=3
If you are talking about what is in between the two sets of parentheses then the answer would be multiplication hope that helped
