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.

Answer:

The correct answer is: {2,4,6,8}

Step-by-step explanation:

Given sets are:

P = {0, 1, 2, 3, 4, 5, 6, 7, 8, 9) and V= {2, 4, 6, 8, 10, 12, 14, 16, 18, 20)

We have to find

P∩V

The symbol is used for intersection of two sets. In intersection, only common elements of both sets are written in result.

So,

P∩V = {0, 1, 2, 3, 4, 5, 6, 7, 8, 9) ∩ {2, 4, 6, 8, 10, 12, 14, 16, 18, 20)

P∩V = {2,4,6,8}

Hence,

The correct answer is: {2,4,6,8}
