Zoey was measuring the sides of a square picture frame. She discovered that the lengths of the sides are 8 inches. What is the approximate diagonal length of the square picture frame?
O A 16 in
OB. 8 in.
C11 in.
OD 4 in

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

answer: about 22.67
