An Obtuse Angle is more than 90° but less than 180°
In the ring of 173-adic integers.
Nine degrees. Its supplement 171 degrees is ninteen times 9 degrees.
There are eight: 108, 117, 126, 135, 144, 153, 162, 171.
171 is a composite because it has more factors than 1 and itself. The factors of 171 are 1, 3, 9, 19, 57, and 171.
If you include 8 and 171, there would be 171-8+1 = 164 If you dont include both, it would be2 less -> 162
The answer is 58. 56+57+58 = 171 171 is the largest palindrome less than 220 that can be divided by three. Further palindromes are: 181, 191, 202 and 212.
108, 117, 126, 135, 144, 153, 162, 171.
