Mateo begins his dive at sea level. He dives down 15 meters, and then rises up 4 meters. He dives again, going down 7 meters. Which equation models Mateo’s movements, and uses the commutative property? (–15) + 4 + (–7) = (–7) + (–15) + (–4)
(–15) + 4 + (–7) = 7 + 15 + (–4)
(–15) + 4 + (–7) = 4 + (–15) + (–7)
(–15) + 4 + (–7) = 4 + 15 + 7

sorry, i can't understand your question. will later if you describe more clearly!

: )

by definition, an arc subtended by a central angle of some given measure has the same measure. so .
