Explanation:
Imagine we have a point
P
with Rectangular (also called Cartesian) coordinates
(
x
,
y
)
and Polar coordinates
(
r
,
θ
)
.
The following diagram will help us visualise the situation better:

We can see that a right triangle is formed with sides
x
,
y
and
r
, as well as an angle
θ
.
We have to find the relation between the Cartesian and Polar coordinates, respectively.
By Pythagora's theorem, we get the result
r
2
=
x
2
+
y

The only properties we can say about
θ
are its trigonometric functions:
sin
θ
=
y
/
r
⇒
y
=
r
sin
θ
cos
θ
=
x
/
r
⇒
x

So we have the following relations:

Answer:
7 to the second power... because 7 times is 49 and 49-49 is 0... so 7 to the second power
Answer is B.
the question says that a total of 108 blue shirts and 96 green shirts are sold, so we calculate the total number of shirts in the respective rows, while ensuring that the total number of shirts in the columns add up to 60 small, 86 medium, and 58 large respectively
