I believe it's 12 because 5*16=80. So, then you would subtract 4 from 16 and gat 12.
Answer:
They reverse each other.
Step-by-step explanation:
A function and an inverse of a function undo what the other does. For example, a function gives an ordered pair of (5,0). Therefore, the inverse would give an ordered pair (0,5).
Perimeter of the triangle, a+b+c
In this case, a=b=c=28
So, perimeter would be 28*3 = 84 cm
