71 degrees
n = 99 degrees compliment = n-18 also, compliment = 180-n therefore n-18 = 180-n 2n = 198 n = 99

The sum of all four interior angles in a quadrilateral must be 360, so the answer would be: 360 - 54 - 25 - 99 = 182
If the sides are 10cm, 17cm and 21cm, the three angles are approx 28, 53 and 99 degrees. It is an obtuse angled triangle.
the answer to 180 degree angle is 72 degree angle.
If it is a triangle then the 3rd angle is 70 degrees
It works out that the other two angles are 29 degrees and 52 degrees. Check: 29+52+99 = 180 degrees
The angles are: 43 degrees. 38 degrees and 99 degrees which all add up to 180 degrees
It is: 180-81 = 99 degrees
n = 99 degrees compliment = n-18 also, compliment = 180-n therefore n-18 = 180-n 2n = 198 n = 99
180 - 99 = 81 degrees.

An angle of 110 degrees is an obtuse angle because it is greater than 90 but less than 180 degrees.
The sum of all four interior angles in a quadrilateral must be 360, so the answer would be: 360 - 54 - 25 - 99 = 182
The measure of the exterior angle of a 11-sided polygon = 360⁰/11 = 32 72/99⁰ = 32 8/11⁰
99 degrees goodluck 99 degrees goodluck
