Triangle ABC has side lengths a= 24, b= 40, and c= 55. What is the measure of angle C? 83.6° 116.2° 23.0° 40.7°
Harlamova29_29 [7]
<h3>Answer:  116.2°</h3>

Work Shown:

c^2 = a^2 + b^2 - 2ab\cos(C)\\\\55^2 = 24^2 + 40^2 - 2*24*40\cos(C)\\\\3025 = 576 + 1600 - 1920\cos(C)\\\\3025 = 2176 - 1920\cos(C)\\\\3025 - 2176  = -1920\cos(C)\\\\849  = -1920\cos(C)\\\\-1920\cos(C) = 849\\\\\cos(C) = (849)/(-1920)\\\\\cos(C) \approx -0.4421875\\\\C \approx \cos^{-1}(-0.4421875)\\\\C \approx 116.243535748231^{\circ}\\\\C \approx 116.2^{\circ}\\\\

The first equation is one of the three variations for the Law of Cosines.

Make sure your calculator is in degree mode.

Which value for x completes the conditional relative frequency table by column? 0. 17 0. 25 0. 40 0. 85.
matrenka [14]

A relative frequency table is a graph that depicts the popularity or pattern of a certain piece of data based on the population sampled. The value of x will be 85.

<h3>What is a relative frequency table?</h3>

A relative frequency table is a graph that depicts the popularity or pattern of a certain piece of data based on the population sampled.

When we examine the relative frequency, we examine the number of times a certain event happens in comparison to the overall number of events.

We have the following equation for the adult column;

\rm  x + 0.15 = 1

\rm  x = 1-0.15\\\\\rm  x = 0.85

Hence the value of x will be 85.

To learn more about the relative frequency table refer to the link;
