The length of a rectangle is one unit shorter than one-sixth of the width, x.

sweet [91]

Lets say that y represents length and x width.
From the text we can write:
y=x/6 - 1

Perimeter we calculate:
P = 2*x + 2*y

now we use y equation from above and put it in perimeter equation:

P = 2*x + 2*(x/6 - 1)
P = 2*(7x/6 - 1)
P = 7x/3 - 2

Answer:

See the attachment

Step-by-step explanation:

A unit circle is one whose radius is 1

sin(90) will have coordinates (0,1)

sin(40)= 0.643

sin(40)= P/H= 0.643/1

cos(40)= B/H= 0.766

Similarly for cos(245)= cos(-65)= -0.423/1

sin(245)= sin(-65)= -0.906
