First, let's assign two variables: one for the name of the limestone statue, and one for the name of the marble statue. 'L' will represent the age of the limestone, and 'm' represents the age of the marble statue.
With the given, we can make two equations:
L = m + 56 (A limestone statue is 56 years older than a marble statue)
L + 12 = 3(m + 12) (In 12 years, the limestone will be three tikes as old as the marble statue)
Thanks to the first equation, we already have a value for L, m + 56.
Input it into the second equation:
(m + 56) + 12 = 3(m + 12)
Simplify:
m + 68 = 3m + 36
Subtract:
68 = 2m + 36
Subtract:
32 = 2m
Divide:
16 = m
Since the limestone statue is 56 years older:
L = 16 + 56 = 72
The marble statue is 16 years old, and the limestone statue is 72 years old.

Answer:
C is the correct answer
Step-by-step explanation:
The square root of ten can be written as:
![\sqrt{10}](https://tex.z-dn.net/?f=%5Csqrt%7B10%7D)
So when you calculate the square root of 10, you would got a number around 3.16 and in this case, 3.16 is between 3 and 4.
Hope this help you :3
Sum would be equal to 720.
so, x-60 + x-40 + 130 + 120 + 110 + x-20 = 720
3x + 240 = 720
3x = 720 - 240
x = 480/3
x = 160
Angle F = x-20 = 160 - 20 = 140
In short, Your Answer would be 140
Hope this helps!
