The short sides of a rectangle are 2 inches. the long sides of the same rectangle are three less than a certain number of inches. sketch and label the sides of this rectangle. use an algebraic expression to represent the length of the long sides.

Let x be the certain number of inches mentioned in the problem. So, three less than this quantity is

This means that you have to sketch a rectangle labelling the short side with 2, and the long sides with

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
