It depends on what is known about the triangle.
to find the missing side of a 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.
the Pythagorean theory
It depends on whether X is the missing side, one of the angles or some other measure of the triangle.

180 minus two known angle = missing angle. Use Pythagoras' theorem to find its missing side.
The third side can be of any length in the interval (2, 128) units of length.
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.
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.

At each vertex of a triangle, an exterior angle of the triangle may be formed by extending ONE SIDE of the triangle.
To find the degree of angle of a side of a triangle, a protractor is needed to measure the angle. Place the '0' on the protractor on the point of the angle and look at the top part to determine degree of angle. To measure the length of a triangle side, a simple ruler can be used to measure the length.
