Please help i don't know what I'm doing!!! :( multiply and simplify cot x( sin x - sec x)
fgiga [73]

Answer:

  cos(x) -csc(x)

Step-by-step explanation:

It is helpful to know the relations between the trig functions:

  \cot{x}=\dfrac{\cos{x}}{\sin{x}}\\\\\sec{x}=\dfrac{1}{\cos{x}}\\\\\csc{x}=\dfrac{1}{\sin{x}}

__

Then the given expression can be simplified as follows:

  \cot{x}(\sin{x}-\sec{x})=\dfrac{\cos{x}}{\sin{x}}\left(\sin{x}-\dfrac{1}{\cos{x}}\right)=\cos{x}-\dfrac{1}{\sin{x}}\\\\=\boxed{\cos{x}-\csc{x}}

Calculate the value of b.<br>(b-15)<br>3b°<br>(2b + 45°<br>Diagram not drawn accurately​
e-lub [12.9K]

Answer:

b = 30

Step-by-step explanation:

The sum of the 2 angles above the line will equal the angle below the line

3b + b - 15 = 2b + 45

4b - 15 = 2b + 45 ( subtract 2b from both sides )

2b - 15 = 45 ( add 15 to both sides )

2b = 60 ( divide both sides by 2 )

b = 30
