let's recall that in an isosceles triangle, the twin sides make twin angles at the bottom/base, so on the triangle on the left-side, if the "vertex" atop has an angle of 116°, then the twin sides below are simply 180° - 116 = 64, split that in half and that's 32° each.
The same is true for the isosceles triangle on the right side. Also recall that a flat-line is always 180°, 32 + 72 + 76 = 180.
Check the picture below.
The ratio of cats to all animals is 12:23.
(X-4, y-9) since it moves left its negative and the y went down makes that negative too

Answer:36 
</h2>
Step-by-step explanation:
Given that
is isosceles triangle.
A isosceles has two sides equal an the third side is the base.
So,
...(i)
Given that length of the base 
Given that the perimeter of the triangle is 
So,
...(ii)
Using (i) and (ii),
