The other acute angle in that triangle is 40 degrees.
If the angles A, B and C forms a triangle, then angle A is 111 degrees.
It is a right angle triangle and the 3rd angle will measure 30 degrees
They each measure 60 degrees
20 degrees
25 degrees
108 degrees, 54 degrees and what ever it take to make 180. 18 degrees.
32 and 71 equals 103 subtract that from 180 and you get your answer of 77 degrees
