Answer:
Sum of all the angles in a triangle = 180 degrees
1st angle = 100 degrees
2nd angle = 25 degrees
Hence , 3rd angle = 180 - ( 100 + 25 )
= 180 - 125
= 55 degrees

Step-by-step explanation:
1st angle = 100
2nd angle=25
3rd angle=? let it be x
We know that sum of angles in triangle=180 so
100+25+x=180
125+x=180
x=180-125
x=55
