Answer:
When Ø = 300°, Ø = 60 degrees.
When Ø = 225°, Ø = 45 degrees.
When Ø = 480°, Ø = 60 degrees.
When Ø = -210°, Ø = 30 degrees.
Step-by-step explanation:
Reference angles are in Quadrant I (0° to 90°).
1. Find 300° (Quadrant IV) on the unit circle. Since it's in Quadrant IV, you use 360 - 300 = 60° to get your answer.
2. Find 225° (Quadrant III) on the unit circle. Since it's in Quadrant III, you use 225 - 180 = 45° to get your answer.
3. The angle 480° is not on the unit circle. To find its corresponding angle between 0° and 360°, use 480 - 360 = 120°. Then, find 120° (Quadrant II) on the unit circle. Since it's in Quadrant II, you use 180 - 120 = 60° to get your answer.
4. The angle -210° is not on the unit circle. To find its corresponding angle between 0° and 360°, use -210 + 360 = 150°. Then, find 150° (Quadrant II) on the unit circle. Since it's in Quadrant II, you use 180 - 150 = 30° to get your answer.

Answer:
7%
Step-by-step explanation:
19,795 - 18,500 = 1295
What percent is 1,295 of 18,500
X/100 = 1295/18,500 (cross multiplication)
= 7%

Answer:
99 miles
Step-by-step explanation:
Length of the trace 444 miles
The couple drove that distance in four days doing as follow:
Lets call x the miles per day they drove
first day x miles
Second day 8 + x miles
Third day 8 + 8 + x miles
fourth day 8 + 8 +8 + x miles
Then we get the equation:
x + ( 8 + x ) + ( 16 + x ) + ( 24 + x ) = 444
Solving for x
4x + 48 = 444 4x = 444 - 48 4x = 396
x = 99 miles
