A submarine is 50 meters below sea level. It goes up 15 meters then goes down 40 meters. What is the submarines' new position relative to sea level

50-15=35+40=75 meters below

Step-by-step explanation:

50-15=35+40=75 meters below

hope it you

step-by-step explanation:

sin(7pi/6 - pi/3)  

= sin(7pi/6 - 2pi/6)  

= sin(5pi/6)  

= sin(pi - pi/6)  

= sin(pi/6)  

= 1/2  

sin 7pi/6 - sin pi/3  

= sin (pi + pi/6) - sin pi/3  

= -sin pi/6 - sin pi/3  

= -1/2 - sqrt(3)/2  

= -(1+sqrt(3))2
