The table below summarizes the 450 members of a university sorority by their majors. This information is also presented as a circle graph.

Find the central angle measure, [tex]$x^{\circ}$[/tex], for the Humanities slice in the circle graph. Do not round.

\begin{tabular}{|c|c|}
\hline Major & \begin{tabular}{c}
Number of \\
Sorority Members
\end{tabular} \\
\hline Business & 54 \\
\hline Sociology & 99 \\
\hline Humanities & 126 \\
\hline Engineering & 81 \\
\hline Biology & 45 \\
\hline Other & 45 \\
\hline
\end{tabular}



Answer :

To determine the central angle measure for the Humanities slice in the circle graph, we can follow these steps:

1. Identify the Total Number of Sorority Members: According to the table, the total number of sorority members is 450.

2. Number of Humanities Members: The table shows that there are 126 members majoring in Humanities.

3. Determine the Fraction of Humanities Members: We calculate the fraction of the total members that the Humanities members represent. This is done by dividing the number of Humanities members by the total number of members.
[tex]\[ \text{Fraction of Humanities members} = \frac{126}{450} \][/tex]

4. Calculate the Central Angle: The total number of degrees in a circle is 360 degrees. To find the central angle measure for the Humanities slice, we multiply the fraction of Humanities members by the total number of degrees.
[tex]\[ x = \left(\frac{126}{450}\right) \times 360 \][/tex]

5. Simplify the Calculation: Evaluating the above expression gives:
[tex]\[ x = \left(\frac{126}{450}\right) \times 360 \approx 100.80000000000001 \][/tex]

Therefore, the central angle measure for the Humanities slice in the circle graph is approximately [tex]\( 100.80000000000001^\circ \)[/tex].
