Answer:
63°
Step-by-step explanation:
The sum of all interior angles of a triangle = 180°
Therefore:
x + 96° + 21° = 180°
x + 117 = 180
Subtract 117 from each side
x = 180 - 117
x = 63°
Let this number be x. The next number is (x+1). And their sum is 57. Then, we have to solve this equation x+x+1=57
