If a radio transmission tower is 190 feet tall how long should a guy wire be if it is to be attached 9 feet from the top and is to make an angle of 21 degrees with the ground?

A guy wire attached to a tower 181 feet from the base (190 - 9) and making an angle of 21 degrees with respect to the ground is 505 feet long.
sin (21) = 181 / x
x = 181 / sin (21)
Note: An angle of 21 degrees with respect to the ground is unrealistic. It is probably more correct to say 21 degrees with respect to the tower, which is 69 degrees with respect to the ground. In this case, the guy wire is 194 feet long.

What fraction is 270 degrees?
270 is an integer and so it would be sensible to represent it as an integer: 270 degrees. There is no requirement in the question to change the measurement unit, and if you do want that then you will need to specify the required unit. I suggest the answer should be 3*pi/2 radians.
How do you know if the pitch of a roof is 10 or 12?
A 12/12 is 45 degrees. If you set a 45 degree piece of wood on the roof it should be level.
What angle should a solar panel pool heater be set at?
There are two angles to consider: North-South direction and inclination up from horizontal. For best performance, face the solar panel generally south at an inclination of 15 to 30 degrees up from horizontal. This will point the face of the panel nearly directly at the sun. Don't stess over the exact angle, you should be fine as long as its close. Hope this helps... In terms of angle, I have read that you should tilt the panel at an angle equal to your latitude geographically. So, LA is 34 degrees LAT, therefore tilt the panel 34 degress for year round installation. If possible it should be tilted accordingly for seasons. I found a web site with the acronym RSPEC (Reduce Swimming Pool Energy Costs) that suggests the following: The collectors should (ideally) face due south and should be angled based upon your latitude. For heating in the summer months subtract 10-15 degrees from your latitude. For heating in the winter months add 10-15 degrees to your latitude and for year round heating install at your latitude.
