I'm not sure what the answers you have mean. sorry! I've solved the problem, though, if that helps at all.

4x + 10y = 57

2x + 5y = 38

5y = 38-2x

y = (38-2x)/5

4x + 10((38-2x)/5) = 57

4x + 2(38-2x) = 57

4x + 76 - 4x = 57

0x + 76 = 57

the answer is no solution because 76 $\neq$ 57

Answer:

arc AC = 111°

Step-by-step explanation:

∠APC is a central angle, so arc AC is equal to the measure of ∠APC.

∠APC and ∠BPC are supplementary. So, m∠APC + m∠BPC = 180

m∠APC + 69 = 180

m∠APC = 111

arc AC = 111°
