Answer:
Learn to find the sine, cosine, and tangent of 45-45-90 triangles and also ... Until now, we have used the calculator to evaluate the sine, cosine, and tangent of an angle. However, it is possible to evaluate the trig functions for certain angles without ... This is because there are two special triangles whose side ratios we know!
Step-by-step explanation:
I would say it’s C because you make X negative
Given:
The line contains the point (-5,-3) and has a slope of -2.
To find:
The graph of the line.
Solution:
The line contains the point (-5,-3) and has a slope of -2. So, the equation of line is

where, m is slope.



Subtracting 3 from both sides, we get


So, the equation of line is
.
Putting x=0, we get



It means, the line also passes through (0,-13).
Plot the points (0,-13) and (-5,-3) on a coordinate plane and connect them by a straight line.
Therefore, the graph of given line is shown below.

L+8=W
L*W=65
sub W from the first equation to second one
L*(L+8)= 65
L^2+8L =65 L^2+8L -65 =0 L=-13 and L=5, length cannot be negative so L=5 is the answer
sub this value in the first equation W=13
