let's put all these options in columns to visualize:

black white
now i'll list all the combos without matching colors (shirt, pants)
red, khaki;
red, black;
red, white;
white, khaki;
white, black;

Answer:
12
Step-by-step explanation:
A straight line is equal to 180. The line AB is 180 degrees. This means 174 + angle = 180 for the angle between point D and B. It must be 6 degrees. This is the same angle as the angle between point A and C.
Line CD is also straight and equal to 180. On the line are the angles, 4k + 90 + 3k + 6 = 180. Solve for k by combining like terms and then using inverse oeprations.
4k + 90 + 3k + 6 = 180
7k + 96 = 180
7k = 84
k = 12
The measurement of angle C is 228°
