Hello!! Original scale: 1 inch = 4 feet. A square with 12-foot sides and a larger square with 15-foot sides. Raphael saw a square patio that was 12-feet long on each side. He wants to build a patio that will be 15-feet long on each side. The change in the scale factor is. The change of scale means that 1 inch represented 4 feet, but now 1 inch represents feet.

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
