The exact value

   =  210°

Step-by-step explanation:

Step(i):-

Given that the inverse trigonometry

We know that the sine function has negative in third quadrant

We have to use trigonometric formula

Step(ii):-

                                                =

Final -

The exact value

the number of possible outcomes that do not show a 1 on the first spinner and show the number 4 on the second spinner is 2.

spinner 1 spinner 2

1                     1

1                     2

1                     3

1                     4

2                   1

2                   2

2                   3

2                   4   = not 1, and 4

3                   1

3                   2

3                   3

3                   4 = not 1, and 4

only 2 outcomes have passed the given condition.
