So, when we're tasked with things like this, rewriting everything in terms of sine and cosine and combining fractions often trivializes things, so doing just that gives us:

\frac{\frac{1}{\cos{x}}-\frac{1}{\sin{x}}}{\frac{\cos{x}}{\sin{x}}-1}= \\\frac{\frac{=(\cos{x}-\sin{x})}{\cos{x}\sin{x}}}{\frac{\cos{x}}{\sin{x}}-\frac{\sin{x}}{\sin{x}}}=\\\frac{-(\cos{x}-\sin{x})}{\cos{x}\sin{x}}*\frac{\sin{x}}{\cos{x}-\sin{x}}=\\-\frac{1}{\cos{x}}

So out expression is 1/cos(x).

Can someone explain how to do it aswell please and thank you
Paul [167]

Answer:

B: 24ft^2

Step-by-step explanation:

Area of triangle = (base x height)/2

Step 1: form an equation

a = (12ft x 4ft)/2

Step 2: solve equation

a = 48ft^2 / 2

a = 24ft^2

*the base is the measurement for the bottom of a triangle while height is the measurement of the length from the bottom to the top of a triangle*

4(2m-5)=2(3m-4)-6m what is the value of M
Schach [20]

Answer:

\frac{3}{2}

Step-by-step explanation:

4(2x - 5) = 2(3x - 4) - 6x =   \\  8x - 20 = 6x - 8 - 6x = \\   8x = 20 - 6  \\  \frac{8x}{8}  =  \frac{20 - 8}{8}  \\  x =  \frac{3}{2}

hope its clear ♡
