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.

The perimeter of the triangle will be 41ft
<h3>The perimeter of a triangle</h3>
The perimeter of a triangle is the sum of all the sides of the triangle
From the given triangle, we need to get the third sidee firse as shown:
h² = 12² + 12²
h² = 144 + 144
h² = 288
h = 17ft
Perimeter = 12 + 12 + 17
Perimeter = 41ft
Hence the perimeter of the triangle will be 41ft

Answer:
A
Step-by-step explanation:
Using the Sine rule in Δ ABC
= , substitute values
= ( cross- multiply )
BC sin38° = 3 sin66° ( divide both sides by sin38° )
BC = → A
