Answer:
B = 160°
Step-by-step explanation:
This is how I solved it (I hope the explanation isn't too confusing):
Since L and K are parallel, I drew a straight line from A to B. By doing this, I'm making a triangle: ΔABC
Then I solved for the angles of the triangle. First, we are given that ∠C = 80° and ∠A = 120°. Although, when I drew the vertical line from A to B, it made a 90° (see attachment).
So what we basically did was break ∠A into two parts: an angle inside ΔABC and one outside. To find the interior angle, simply subtract 90° from 120° to get 30°.
There are 180° in a triangle, so add the two interior angles you know:
30° + 80° = 110°
Then subtract 110° from 180° to find the final interior angle which is:
180° - 110° = 70°.
To find the measure of angle B, you must add all of the parts together, so the 90° outside angle and the 70° interior angle:
90° + 70° = 160°
40; base it off of the y-intercept [C]. What is the unit of measurement?
Answer:
$3.94
Step-by-step explanation:
You will need to use the compound interest formula for this.

P = initial balance
r = interest rate
n = number of times compounded annually
t = time
Your equation will look like this:
= 3.94
Answer:
Situation Best measure
1. The weights of wrestlers on the team varies by 74 lbs. range
2. The most popular M&M's color is green. mode
3. The mean price for an mp3 download is $1.96. mean
4. Half of the students in 3rd hour PE are 15 or older. median
Step-by-step explanation:
1. The weights of wrestlers on the team varies by 74 lbs. This is the range, the difference between the maximum and the minimum value.
2. The most popular M&M's color is green. This is the mode, the value more repeated.
3. The mean price for an mp3 download is $1.96. This is the mean.
4. Half of the students in 3rd hour PE are 15 or older. This is the median, the value in the half of the values
