Okay so are the formulas the same as before? There are 2 other angles given now..

OK.....

1 the arc C all of the way around to A is 2 * (5x+2)

This same arc is equal to 360 - 87 - 39 Right? Can you do it now?

2 ARC YZ = 2 * 59 This plus the 75 degree arc = 2 * 59 + 75

THIS plus the 17x-20 arc = 360 degrees (the entire circle)

so 2 * 59 + 75 + 17x -20 = 360 Right? Need more?

Okay so I would have to do 2*4 and that would be 5x+4=234

And eventually I would get 46

For the next one...I'm not sure actually. 17x-20+268=360??

Here is where you went wrong:

close RP 2*(5x+2) = 360 - 87-39 =======> 2*(5x+2) does not equal 5x + 4

10x +4 = 234
