Final answer:
Without specific angle measurements, an exact answer cannot be provided. However, in general, the missing angle in a triangle can be calculated by subtracting the given angles from 180 degrees, and in a polygon, by subtracting the given angles from the total sum of interior angles which is calculated by (n-2) * 180, where n is the number of sides.
Step-by-step explanation:
Since the question has not provided specific angle measures, it's difficult to provide an exact answer. However, I can show you a general method to calculate missing angles in a triangle or other polygons. In a triangle, the sum of angles always equals 180 degrees. Thus, if two angle measurements are given, then you can subtract their sum from 180 to determine the measurement of the missing angle. For example, if one angle is 90 degrees and the second angle is 30 degrees, the third angle would be 180 - 90 - 30 = 60 degrees.
In a polygon, the sum of interior angles can be found using the formula (n-2) x 180, where n is the number of sides. If you know the measure of a certain number of angles, you can add them together and subtract from the total sum to find the measure of the missing angles.
