See this figure. http://puu.sh/szNCt.png
a) $cos B = \frac{20}{24} 

$ x
enter in calculator invcos or cos^-1 of 4/5 and you should get B ≈ 37 degrees (make sure your calculator is in degrees and not radians)
b) Since this is a right triangle,
C ≈ 53 degreesc) By the Pythagorean Theorum, AC is approximately 13.27.
$AC^2 + 20^2 = 24^2$
AC ≈ 13
Hope this helps! =)

A typical television newscast has three cameras. The center camera directly faces the news anchors desk. The other two cameras a

Now we'll continue to use the +/- 30 degree coverage for the other two cameras. The second camera is aimed at 45 degrees, so it's range of coverage is 15 degrees to 75 degrees (45 +/- 30). Notice that the range from 15 degrees to 30 degrees is covered by 2 cameras. Now the 3rd camera is pointed at -45 degrees, so its coverage is from -15 degrees to -75 degrees. It also has an overlap with the 1st camera from -15 to -30 degrees. The total coverage of all three cameras ranges from -75 degrees to 75 degrees. That means that an arc of 150 degrees in total is covered by all three cameras.</span>
