To calculate for cos X given that sin X=0.6 and is in Quadrant we proceed as follows:
sin X=0.6
Thus implies that:
x=arcsin 0.6
x=36.97
given that X is in the Quadrant ii then the value of x will be:
180-36.97
=143.13
hence cos X will be:
cos X=cos 143.13
cos X=-0.8

Dimensions of rectangle are:
Length = 26 cm
Width = 9 cm
Step-by-step explanation:
Perimeter of rectangle = 70 cm
Width= x
Length = 2x+8
We need to find the value of length and width of rectangle.
The formula used is:

Putting values:

So, Value of Width = x = 9 cm
Value of Length = 2x+8 = 2(9)+8 = 18+8=26 cm
So Dimensions of rectangle are:
Length = 26 cm
Width = 9 cm
