A consistent freak act of nature allowed the Egyptians to harness the capabilities of the Nile River. While the majority of Egypt was and still is covered with the aforementioned sand, the river<span> basin next to the Nile boasts wildlife and fertile soils. This is all due to the predictable rise and fall of the Nile's water levels each year, known as </span>inundation<span> (rise) and </span>relinquishment<span> (fall). During the inundation period, which takes place sometime around July, water would rise and fill canals made by Egyptian laborers. Sometime around the end of October, the river would begin to recede, leaving rich silt deposits.</span>

Find the measure of each angle in degrees and radians.<br>​
Paul [167]

Problem 9

This is not correct. It would be correct if the longer arc mark was not there. However, because it is there, you have to travel 360-30 = 330 degrees in the negative direction. So the angle shown along that arc is -330 degrees which converts to -11pi/6 radians.

====================================

Problem 10

The spiral arc almost wraps itself around 2 times over, effectively almost making two full revolutions.

1 revolution = 2pi radians

2 revolutions = 4pi radians (multiply both sides by 2)

Subtract off pi/3

4pi - pi/3 = 12pi/3 - pi/3 = 11pi/3

11pi/3 represents the radian measure of the spiral arc

Convert to degrees

11pi/3 radians = (11pi/3)*(180/pi)

11pi/3 radians = (11/3)*180

11pi/3 radians = 11*180/3

11pi/3 radians = 11*60

11pi/3 radians = 660 degrees

====================================

Problem 11

Add pi/2 radians to the angle measure shown

pi/2 + 7pi/18 = 9pi/18 + 7pi/18

pi/2 + 7pi/18 = 16pi/18

pi/2 + 7pi/18 = 8pi/9

The full angle in radians is 8pi/9 radians

Now convert to degrees

8pi/9 radians = (8pi/9)*(180/pi)

8pi/9 radians = (8/9)*180

8pi/9 radians = 8*180/9

8pi/9 radians = 8*20

8pi/9 radians = 160 degrees

====================================

Problem 12

Add pi/2 radians (aka 90 degrees) to pi/9 to get

pi/2 + pi/9 = 9pi/18 + 2pi/18

pi/2 + pi/9 = 11pi/18

This represents the red angle shown in the diagram below.

Subtract this found angle from 4pi, which represents 2 full revolutions

4pi - 11pi/18 = 72pi/18 - 11pi/18

4pi - 11pi/18 = 61pi/18

The spiral mark shown in the diagram is 61pi/18 radians

Convert to degrees

61pi/18 radians = (61pi/18)*(180/pi)

61pi/18 radians = (61/18)*180

61pi/18 radians = 61*180/18

61pi/18 radians = 61*10

61pi/18 radians = 610 degrees

Given the picture below, find x and both angles.
Lisa [10]

Answer:

x =42.5

x+8 =50.5

3x+2 =  129.5

Step-by-step explanation:

The two angles shown are supplementary, so they add to 180

x+8   + 3x+2 = 180

Combine like terms

4x+10 = 180

Subtract 10

4x = 170

Divide by 4

x =42.5

x+8 = 42.5+8 = 50.5

3x+2 = 3*42.5 +2 = 127.5 +2 = 129.5
