Answer:  1) c    2) a     3) d

<u>Step-by-step explanation:</u>

\cos \theta = \dfrac{adjacent}{hypotenuse}\quad \\\\\\\cos 42.1=\dfrac{4.7}{x}\\\\\\x=\dfrac{4.7}{\cos 42.1}\\\\\\\large\boxed{x=6.33}\\

******************************************************************************************

Reference angle is the angle measurement from the x-axis.  <em>There is no such thing as a negative reference angle.</em>

-183°  is 3° from the x-axis so the reference angle is  \large\boxed{3^o}

*******************************************************************************************

Coterminal means the same angle location after one or more<em> </em>rotations either clockwise or counter-clockwise.

To find these angles, add <em>or subtract</em> 360° from the given angle to find one rotation, add <em>or subtract</em> 2(360°) from the given angle to find two rotations, etc.

To find ALL of the coterminals, add <em>or subtract</em> 360° as many times as the number of rotations.  Rotations can only be integers. In other words, you can only have ± 1, 2, 3, ... rotations. You cannot have a fraction of a rotation.

Given: 203°

Coterminal angles: 203° ± k360°, k ∈ <em>I</em>
