If the 13 is the longest side of that right triangle, then the missing side is 5 . If 'c' is the longest side of that right triangle, then the missing one is 17.692 (rounded).

A triangle always has 180 units. You would have to add up the two sides and subtract that from 180.
It can be found by: hypotenuse squared minus known side squared = unknown side squared
I don't think there is enough information to answer the question, first of all, is it a right triangle? Second, is the the 13cm the hypotenuse. Assuming that 13cm is the hypotenuse, and the triangle is a right triangle, the equation would be 49+x^2=169
The missing side of a right triangle is called the hypotenuse. This side is opposite the right angle and is the longest side of the triangle.
The way to find the missing side of a triangle-THIS ONLY WORKS ON RIGHT ANGLED TRIANGLES-is square both sides seperately and then add them together to give you the square of the missing side-find the square root and that is the size of the missing side-eg. if you have a RIGHT ANGLED TRIANGLE with sides of 3inch and 4inch then (3x3) + (4x4) = 25 so the square root of 25 is 5 meaning the missing side is 5inch.
Pythagorean Theorem: a2 + b2= c2 where c is the hypotenuse of a right triangle. Hypotenuse is the side of a right triangle opposite to the right angle.
180 minus two known angle = missing angle. Use Pythagoras' theorem to find its missing side.
If the 13 is the longest side of that right triangle, then the missing side is 5 . If 'c' is the longest side of that right triangle, then the missing one is 17.692 (rounded).

Surely you know how to find the third side of a right triangle, when you know the lengths of the other two. Find it, and then add up the lengths of the three sides to get the perimeter.
A triangle always has 180 units. You would have to add up the two sides and subtract that from 180.
It depends on what is known about the triangle.
The length of the other side is: 28.6 cm

It can be found by: hypotenuse squared minus known side squared = unknown side squared
