If the point
is on the unit circle, what is x?

1/2

Step-by-step explanation:

If y is the √3/2 on the unit circle, x must be either 1/2 or -1/2.

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2
