Problem 1
<h3>Answer: choice B) They are supplementary angles</h3>
--------------
Explanation:
The two angles combine to form a straight angle (which is 180 degrees). Another term for these angles is "linear pair" since they form a straight line.
=================================================
Problem 2
<h3>Answer: choice B) x = 7</h3>
--------------
Explanation:
The diagonal is never used in this problem. For any rhombus, the four exterior sides are always the same length.
=================================================
Problem 3
<h3>Answer: Choice D) 62 degrees</h3>
----------------
Explanation:
We use the angle addition postulate. This allows us to combine angles BAC and CAD to form angle BAD.
(angle BAC)+(angle CAD) = angle BAD
30 + x = 92
x = 92-30
x = 62
angle CAD = 62
Add the whole numbers.
Then add the numerators.
2 2/6 + 3 2/6 = 5 4/6
Simplify the fraction
5 2/3
Answer:
1.5 meters
Step-by-step explanation:
We know that the sum of all of the data in a set = average * number of data.
Therefore, the sum of the first 10 is 1.5 * 10 = 15 meters, the sum of the second 10 is 1.48 * 10 = 14.8 meters and the sum of the last 2 is 1.6 * 2 = 3.2 meters for a total of 15 + 14.8 + 3.2 = 33 meters. This means that the mean is 33 / 22 = 1.5 meters.
