The area of a square can be found using the equation a = s², where a is the area and s is the measure of one side of the square. match the equation for how to solve for the side length of a square to its description. a square has an area of 81 in2. s=812−−−√ in. s=81−−√ in. s = 81² in. s = 81 in.

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
