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? A.(–15) + 4 + (–7) = (–7) + (–15) + (–4) B.(–15) + 4 + (–7) = 7 + 15 + (–4) C.(–15) + 4 + (–7) = 4 + (–15) + (–7) D.(–15) + 4 + (–7) = 4 + 15 + 7

the answer is b.

step-by-step explanation:

by the trigonometric ratio tangent, tangent equals opposite divided by adjacent.

therefore, tan(50) equals ac/3

multiply each side by 3 to get: ac=3tan(50)

the answer is b.
