$sinx.tanx=secx-cosx\\
\\
sinx.\frac{sinx}{cosx}=\frac{1}{cosx}-cosx\\
\\
\frac{sin^2x}{cosx}=\frac{1-cos^2x}{cosx}\\
\\
\frac{sin^2x}{cosx}=\frac{sin^2x}{cosx}$

Let C represent the cost in dollars and R represent the revenue in dollars. What is the break-even point? Use a table to help if

swat32

The break even point is when C and R are equal....so set them equal

36x + 200 = 76x
200 = 76x - 36x
200 = 40x
200/40 = x
5 = x

C = 36(5) + 200 R = 76(5)
C = 180 + 200 R = 380
C = 380

so the break even point is 380

Find m∠1 if m∠2=73°, m∠3=107°, m∠4=92°.

Nata [24]

If you are describing a quadrilateral, then the answer is
m1 + 73 + 107 + 92 = 360
m1 + 272 = 360
m1 = 360 - 272
m1 = 88 degrees.
If it is anything but a quadrilateral, it would be a good idea to state what it is.

Answer: w =1 L=6

Step-by-step explanation:

What is Perimeter = 2 L + 2W

2L + 2B =14

L = 2W + 4

2(2W + 4) + 2W = 14

4W +8 +2W =14

6W=14-8

W=1

L=2W +4= 6
