The width of a rectangle is 5 3/4 inches. The length is three times its width. What is the perimeter?

perimeter=46.5 inches

Step-by-step explanation:

=

=

perimeter of rectangle =2(l+b)

  (since their denominator are same u can add their numerator)

  inches

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
