The reference angle is the smallest angle between the terminal side and the x-axis.

(1)\ \theta = 300^o

300 degrees is in the 4th quadrant.

So, the reference angle is

\alpha = 360 - \theta

\alpha = 360 - 300

\alpha = 60^o

Hence, the reference angle of 300 degrees is 60 degrees

(2)\ \theta = 225^o

225 degrees is in the 3rd quadrant.

So, the reference angle is

\alpha = \theta - 180

\alpha = 225 - 180

\alpha = 45^o

Hence, the reference angle of 225 degrees is 45 degrees

(3)\ \theta = 480^o

480 degrees is in the 2nd quadrant (i.e. 480 - 360 = 120)

So, the reference angle is

\alpha = 180 - \theta

\alpha = 180 - 120

\alpha = 60^o

Hence, the reference angle of 480 degrees is 60 degrees

(2)\ \theta = -210^o

-210 degrees is in the 2nd quadrant (i.e. 360 - 210 = 150)

So, the reference angle is

\alpha = 180 - \theta

\alpha = 180 - 150

\alpha = 30^o

Hence, the reference angle of -210 degrees is 30 degrees

In which way was the issue of women's suffrage tied to industrialization.
Alexxandr [17]
Answer:Women were being left at home more frequently as men went off to factories.Explanation:Female suffrage or female vote refers to the right to vote exercised by women and therefore the political and constitutional right to vote for elected public office as well as to be voted. The suffrage therefore covers the asset, which determines who is entitled to exercise the vote as the so-called liability, which refers to who and under what conditions they have the right to be elected. The founding moment of Sufragismo was in 1848 with the Declaration of Feelings of Seneca Falls in the United States and culminated a hundred years later, in 1948, with the Universal Declaration of Human Rights that recognizes women's suffrage as a universal human right.
