Step-by-step explanation:

after you draw a unit circle you will find the answer

cosec(3pi)=1/sin(3pi)

sin3pi=sinpi=0

so cosec3pi=1/0 which is undefined.

Consider the sequence of steps to solve the equation: 3(x − 4) + 5x = 9x − 36 Given ⇒ 3(x − 4) + 5x = 9x − 36 Step 1 ⇒ 3x − 12 +
7nadin3 [17]

In Step 6, the equation is ...

  -12 = x - 36

In step 7, the equation is ...

  -12 +36 = x -36 +36

Clearly, to get to step 7, 36 has been added to both sides of the equation.

Adding 36 to both sides of the equation is justified by ...

... C) Addition Property of Equality

_____

<em>More about the addition property of equality</em>

The addition property of equality says you can add the same value to both sides of an equation without changing the values of the variables that make the equation true. Here, x=24 makes the equation of step 6 true, and x=24 makes the equation of step 7 true.

Answer:

(For the first two questions I do believe that you will need a protractor to calculate the angles.)

15) -(\frac{7\pi }{18} )\\ measures out to -70° in order to display that the angle would be in quadrant IV (the bottom right quadrant.)

The first image attached shows where the angle should be located.

16) \frac{\pi }{3} is equal to 60° (the line you draw will be in quadrant 1 (the top right quadrant))

17) 350° is \frac{35\pi }{18} or 6.11 (the answer depends on the format the professor wants.)

18) 240° is -(\frac{4\pi }{3}) radians or -4.19 (I am rounding to the nearest hundredths place the unsimplified answer is −4.18879020...)
