Identify the reference angle es001-1. Jpg for each given angle, es001-2. Jpg. Es001-3. Jpg degrees. Es002-1. Jpg degrees. Es003-

julia-pushkina [17]

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

Why does hamilton think judges should be appointed permanently rather than on a periodic basis? permanent appointments allow for

Lana71 [14]

Hamilton thinks judges should be appointed permanently rather than on a periodic basis because periodic appointments would destroy a judge’s independence.

Alexander Hamilton was an American revolutionary. He was also a statesman and the Founding Father of the United States. He played a key role in promotion and interpretation of the constitution.

Permanent appointments would help to regulate more as well ensure greater independence of the judge.

Periodic appointment on the other hand would destroy a judge independence as he/she can be transferred or impeached anytime that fosters insecurity and lack of motivation to work.

Thus, permanent appointments is the only option.
