Okay, so 2/3 times 8 would be 16/3 but to simplify that you would do 16 divided by 3 and you would get 5 1/3. I hope I got this right
Answer:

Answer:
Angles C and D are what I think are called Supplementary angles. Therefore they equal 180 degrees.
Step-by-step explanation:
If you subtract the measure of angle D by 180 degrees then you should get the measure of angle C which is 56 degrees. I don't really know what they are asking for in the first question. You didn't put any of the choices. :)) Think this may be right.
