I don't think any of them are the answer.
S = (n-2) x 180 to find the total angles.
5-2*180
3*180
540
540-86-140-138-59=117
C is my answer of ask other sources tho. Ok
Answer:
23
Step-by-step explanation:
Suppose,
the first number = x
the second number = x+1
the third number = x+1+1 = x+2
Question wise,
x+x+1+x+2 = 72
3x+3 = 72
3x = 72-3 = 69
x = 69/3 = 23
so the numbers are,
23,(23+1)=24 and (23+2)=25
