ANSWER
The length of the rectangular field is 99 yards
EXPLANATION
Given information
The perimeter of a rectangle field is 372 yards
The width of the field is 87 yards
To find the length of the rectangular field, follow the steps below
Step 1: Write the formula for finding the perimeter of a rectangular field
Step 2: Substitute the given data into the formula in step 1
Hence, the length of the rectangular field is 99 yards
Answer:
Only Graph D
Step-by-step explanation:
A trend line indicates the general course (or average course) of the points on the graph. In Graph C, the general trend seems to intercept at a positive y-value. In Graph D, the trend will continue past the X-axis and intercept at the negative Y-axis.

sin
(
x
+
y
)
=
621
629
or
−
429
629
depending on the quadrant in which sine and cosine lie.
Explanation:
Before we commence further, it may be mentioned that as
cos
x
=
8
17
,
x
is in
Q
1
or
Q
4
i.e.
sin
x
could be positive or negative and as
sin
y
=
12
37
,
y
is in
Q
1
or
Q
2
i.e.
cos
y
could be positive or negative.
Hence four combinations for
(
x
+
y
)
are there and for
sin
(
x
+
y
)
=
sin
x
cos
y
+
cos
x
sin
y
, there are four possibilities.
Now as
cos
x
=
8
17
,
sin
x
=
√
1
−
(
8

)
2
=
√
1
−
64
289
=
√
225
289
=
±
15

and
as
sin
y
=
12
37
,
cos
y
=
√
1
−
(
12

)
2
=
√
1
−
144
1369
=
√

1369
=
±

Hence,
(1) when
x

sin
(

=

(2) when
x
is in
Q

and

sin

(3) when

sin
(

=

(4) when
x
is in
Q
4
and
y
is in
Q
1
sin
(
x
+
y
)
=
−
15

Hence,
