To find the back azimuth, you add 180 degrees to the original azimuth if it is less than 180 degrees, or subtract 180 degrees if it is 180 degrees or more. For an azimuth of 130 degrees 15' 20", adding 180 degrees gives you a back azimuth of 310 degrees 15' 20".
Yes, it is.

temperature rose 10 degrees
The temperature rose 20 degrees in 5 hours (from 10 am to 3 pm). Therefore, the temperature rose an average of 4 degrees per hour.

temperature rose 10 degrees
Well, darling, if the temperature was -6 degrees Celsius and then rose to 9 degrees Celsius, the temperature rose by a whopping 15 degrees. Math doesn't lie, honey! So, grab a sweater for the cold and some sunscreen for the heat, because that temperature just went from "brrr" to "ahh" real quick.
The temperature can be as high as 15 to 20 C degrees (35-55) degrees.
When it is 12 noon at Greenwich (0 degrees longitude), it is 20 degrees west of Greenwich. Since the Earth rotates at 15 degrees per hour, you can calculate the time difference by dividing 20 degrees by 15, which equals approximately 1 hour and 20 minutes. Therefore, it would be 10:40 AM at the location that is 20 degrees west when it is 12 noon at Greenwich.

height = 15 ft base = 20 ft angle of elevation = arctan (15/20) = 36.87 degrees
