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.
It depends on what is known about the triangle.
to find the missing side of a triangle
At each vertex of a triangle, an exterior angle of the triangle may be formed by extending ONE SIDE of the triangle.
they are all the same length
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.

to find the missing side of a triangle
180 minus two known angle = missing angle. Use Pythagoras' theorem to find its missing side.
to find the missing side of a right triangle you need the pythagorean theorem. A2 + B2 = C2. c is the longest side and a and b is the other sides. no particular side is a or b just the longest side is c.

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.
If it is an isosceles triangle then the missing side is 40 cm but for any triangle the sum of its two smaller sides must be greater than its longest side.
