Use the net as an aid to compute the surface area of the triangular prism. dimensions: 11, 15, 16, 17

step-by-step explanation: as sides and hieghts are not mentioned so

i assumed myself that

one base side = 11

second base side = 15

third base side= 16

height= 17

surface area = (surface area of lower base) + (surface area of uper base)+{( one base side +second base side + third base side)}×height

                  =     872

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
