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

******************************************************************************************
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 
*******************************************************************************************
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>

I'm not sure what you mean by 'written method' but the sum is 2,654.
Answer:
This is the equation of a line with slope of 1 and the intercept point wit the 'y' axis is (0, 1.5)
Step-by-step explanation:
Lines have the following equation: y=mx+b, where 'm' is the slope and b is the interception with 'y' axis when 'x'=0
The attached pictures shows the equation of the line in a graph
Answer:
for the second picture: the answer is 15 hours
Step-by-step explanation:
174 miles is for 3 hours, divide that by 3 to find how many miles per hour it is, 870 divided by 58 will give you the number of hours; 15. hope this helps!
