The pairs of angles that have equal measures are:
- LJP
- NJR
- MJP
- PJR
The pairs of angles that do not have equal measures are:
- MJK
- PJR
- KJR
- MJP
- KJL
- LJM
When two lines or rays converge at the same point, the measurement between them is called a "Angle."
It is given that:
Both MJK and PJR can be seen as (Unequal angles)
The angle MJK is ( 90 degrees), then angle PJR will be ( 48 + 46 )= 94 degrees
Both LJP and NJR can be seen as ( Equal angles)
The measure of angle LJP = 48 + 46 + 48 = 142 degrees
The measure of angle NJR = 48 + 48 + 46 = 142 degrees
KJR & MJP = Unequal
The angle KJR will now be [ 360 - (46+48+48+46+90) ]
= 82 degrees
The angle MJP will be ( 94 degrees)
Both KJL & LJM are Unequal, then
The angle KJL will be 42 degrees, then angle LJM will be ( 90 - 42 )
= 48 degrees

Answer:
Step-by-step explanation:
We have the standard deviation for the sample, so we use the t-distribution to solve this question.
The first step to solve this problem is finding how many degrees of freedom, we have. This is the sample size subtracted by 1. So
df = 20 - 1 = 19
99% confidence interval
Now, we have to find a value of T, which is found looking at the t table, with 19 degrees of freedom(y-axis) and a confidence level of . So we have T = 2.861.
The margin of error is:
In which s is the standard deviation of the sample and n is the size of the sample.
The format of the confidence interval is:
In which is the sample mean
So
