Reptile [31]
We know that
in the IV quadrant
cos theta is positive
and 
sin theta is negative
so
cot theta=cos theta/sin theta--------> cot theta must be negative
sec theta=1/cos theta------> sec theta must be positive

a childs desk is made so that the dimensions are 2/3 the dimensions of a full size adult desk supposed to top of the full-size t
Sonja [21]

The perimeter and area of the top of the child's desk are 120 inch and 864 inch² respectively.

<u><em>Explanation</em></u>

Dimensions of the top of the adult's desk :  Length = 54 inches and Width = 36 inches.

As the dimensions of the child's desk are \frac{2}{3} of the dimensions of the adult desk, so....

Length of child's desk = 54*\frac{2}{3} = 36 inches and

Width of child's desk =36*\frac{2}{3}=24 inches.

So, the perimeter of the top of the child's desk =2(length+width)= 2(36+24)=120 inches.

and the area of the top of the child's desk =length*width=36*24=864 inch²

-x -1 = -2x + 7

-x + 2x = 7+1

x = 8

Putting x in (1)

y = -8 - 1

y = -9
