The 4 interior angles of any 4 sided quadrilateral add up to 360 degrees
The third angle is 34.5 degrees
The third angle is (128 degrees) minus (the second angle).
180-105-32 = 43 The third angle measures 43 degrees
25 degrees
180o - 100o - 40o= 40o=====
The third angle measures 18 degrees.
The third angle is 34.5 degrees
The third angle is (128 degrees) minus (the second angle).
77 degrees

To find the measure of the third angle of a triangle, you can use the fact that the sum of all three angles in a triangle is always 180 degrees. So, if one angle measures 50 degrees and the other measures 85 degrees, you can subtract their sum from 180 to find the measure of the third angle. Therefore, the third angle would measure 180 - 50 - 85 = 45 degrees.
180-105-32 = 43 The third angle measures 43 degrees
25 degrees
The missing angle measure is 100 degrees.
