An interior angle in a 13-gon can have any measure between 0 and 360 degrees (excluding the two end values), subject to the constraint that the sum of these angles is (13-2)*180 = 1980 degrees.
If (and only if) the 13-gon is regular - and there is no reason to assume that it is - each angle will be 1980/13 = 152.3 degrees.
The angle would be .4 if you rounded it to the nearest 10th degree
900/7 = 128.6 degrees rounded to the nearest tenth
27.7 Rounded to the nearest tenth. Just do 360 divided by 13.
60.255 degrees (rounded)
It is: 360/11 = 32.73 degrees
The angle would be .4 if you rounded it to the nearest 10th degree
900/7 = 128.6 degrees rounded to the nearest tenth
Each interior angle measures 128.57 degrees rounded
27.7 Rounded to the nearest tenth. Just do 360 divided by 13.
Using trigonometry the angle of elevation is 77 degrees rounded to the nearest degree
6.5
The answer rounded to the nearest tenth is 25 meters.
tan-1(0.8) = 38.65980825 degrees or 38.7 degrees to the nearest tenth.
32.7 A+
It is: tan^-1*(0.8) = 38.7 degrees
You can measure it. Or you can measure some other quantities (for examples, the lengths of the sides of a triangle), and calculate the angle using trigonometry.
Each exterior angle will measure 360/18 = 20.0 degrees
