Question
Are vertical angles. Find value of x.
- 4
- 2
- 1
- 3
Hint:
- When two lines intersect, four angles are formed. There are two pairs of non-adjacent angles these pairs are called vertical angles
The correct answer is: 1
Solution:
- We have been given two vertical angles in the question 5𝑥° 𝑎𝑛𝑑 (𝑥 + 4)°
- We have also been given four options from which we have to choose the appropriate answer to find the value of x.
Step 1 of 1:
We have given 
and 
are vertical angles
We know that vertical angles are equal in magnitude
So,
5x = x + 4
4x = 4
x = 1
Hence, Option C is correct.
Hence, Option C is correct.

Use the given scatter plots to answer the questions.
a) Does this scatter plot show a positive association, negative association, or non-association? Explain why.
b) Is there an outlier(s) in this data set? If so, approximately how old is that person and how much does he or she make in allowance each week?
c) Is this association linear or non-linear? Explain why.
d) What can you say about the relationship between your height and your allowance?
e) Do you think that being older means that you will get more allowance? In other words, do think this relationship is a causation or a correlation?
Causation explicitly applies to cases where one action causes the outcome of another action. Whereas, correlation is simply a relationship.
