Complementary angles sum upto 90°
so the complement of 9° = 81°
Since
, we know that

.
Now assuming
denote the mean and standard deviation of
, respectively, then we know right away that
and
.
So,
The answer to your questions is 11 because PEMDAS. () exponents multipication division addition and subtraction.
Answer:
The length=16cm and the width=8cm.
Step-by-step explanation:
Given that the length is twice the breadth or width of the rectangle
Let's assume that the breadth of the rectangle is x.
Thus the length is 2x.
Given perimeter=48cm
The formula for the perimeter of a rectangle is 2(l+b) where l is length and b is breadth.
2(x+2x)=48
(3x)=48/2
3x=24
x=8cm
2x=16cm
