The laws of sines is already indicated in the provided images.
1. sin20/3.3 = sinC/5.4
Thus, angle C is 34.03 degrees. To find angle B: 180 - 20 - 34.03 = 126 degrees. Using the law of sines,
sin20/3.3 = sin(126)/b
b = 7.8 units
From this answer, we can already tell that the answer is letter C: <span>3 units and 7.8 units.
2. Angle J = 180 - 120 - 40 = 20 degrees. Then,
sin(20)/2 = sin(120)/k
k = 5.1 units</span>
Answer: The answer is C. The leading coefficient is -3 and the constants is 2.
explanation: I just took the test
12 -2x < 16
First, subtract 12 from both sides.
-2x < 16 - 12
-2x < 4
Divide both sides by -2
x > -2 (you switch the < sign with > when divided by a negative).
Because it is not greater than/less than or equal to, it is an open circle at -2. Any number that is greater than -2 means it's shaded to the right, the answer's B.

Answer: 10:40 AM</h3>
====================================================
Explanation:
Add the minutes for now
55 minutes + 10 minutes = 65 minutes = 60 minutes + 5 minutes = 1 hour, 5 minutes
The minute portions add to 1 hour, 5 minutes. The hour portions add to 3+1 = 4.
Add on the "1 hour, 5 minute" portion and we get 5 hours, 5 minutes
This is the total duration of the round trip hike. Keep in mind that this does not include any time spent with Jennifer resting at the top of the mountain. This time duration assumes that once she gets to the top, she pretty much starts the hike back down the mountain.
----------------------------
Now convert 3:45 PM to military time. We add 12 hours to get 15:45
Subtract off 5 minutes to get 15:40
Then subtract off 5 hours to get 10:40, which converts back to 12-hour time notation to be 10:40 AM
