The length of a rectangle is 3 more inches than the width. find the length and width of the rectangle is the perimeter of the rectangle is 54 inches. #7 write an equation that represents the situation. explain any variable used. #8 solve the equation. show your work. state your solution as a complete sentence

Part A:

Let the width of the rectangle be = x inches

As given, the length of a rectangle is 3 more inches than the width so let the length of the rectangle be = x+3 inches

Perimeter is given as = 54 inches

Perimeter =

Equation becomes:

=54

Part B:

Solving the equation we get

Hence, the width of the rectangle is 12 inches

Length = x+3 = 12+3 = 15 inches

Hence, length of the rectangle is 15 inches.

(sin 42)/31. = sinx)/37

sinx = 37 (sin42)/31

= 37× 0.66/31 = 0.787

x= 51.9

other angle opposite to y = 180-51.9-42

= 180- 93.9 =86.1

so

sin42)/31 = sin 86.1)/y

0.021 = 0.997 /y

y= 0.997/0.021 =47.47
