Find the value of n.​

Step-by-step explanation:

The ratio 2.5 m to 60 cm =

250 cm : 60 cm

= 1 : 60/250

= 1 : 0.24

so, n = 0.24

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
