Determine which characteristics are true of vertical angles
2 answers:
Answer:
- They are formed by intersecting lines.
- They are opposite of each other.
- They are congruent.
Step-by-step explanation:
When two lines intersect then they form two pairs of angles known as vertical angles. They are opposite to each other and have same measure.
i.e. they are congruent.
Hence, the characteristics that are true for vertical angles :
- They are formed by intersecting lines.
- They are opposite of each other.
- They are congruent.

Step-by-step explanation:
To compare both scored we need to standardize the scores using the following equation:
Where x is the score, m is the mean and s is the standard deviation. So, 82 on chemistry is equivalent to:
Because the mean of the scores on the chemistry final exam is equal to 75 and the standard deviation is 15
At the same way, 80 on Calculus is equivalent to:
Because the mean of the scores on the calculus final exam is equal to 83 and the standard deviation is 13
Now, we can compare the values. So, taking into account that -0.2308 is lower than 0.4667, we can said that the student do better in Chemistry.
Answer:
132
Step-by-step explanation:
Triangle formula is 1/2 bh (4x3/2) is 6 (4 triangles)=24
Base is 6x8=48
sides are 6x5=30 then multiply by 2 of the sides =60
