Lou didn't break the sects up so he got the answer wrong. This is the correct method.....
Sect #1
6 - 3 = 3
3 x 3 = 9
Sect #2
6 - 3 = 3
3 x 8 = 24
24 + 9 = 33
Sorry if i didn't explain good or got the answer right. Im young.
The answer will be 587,328 whenever added!

Angle ACB = 90 - angle DCA = 90-50=40
Answer is option C. 40
===========================
Part 2:
