1). Take the information you have.
2). Collect and write down all the formulas, equations, and rules you know
that tell some kind of connection or relationship between the information
you have and the length of 'a' .
3). Use the information you have, and the relationship between that information
and the length of 'a', to find the length of 'a'.
If there is no length for the hypotenuse you have to use the Pythagorean Theorem. If there are two sides missing and a reference angle you could use Trigonometry.
The third side can be of any length in the interval (2, 128) units of length.
To find a missing dimension of an object find the size of its covering properties.

The length of the missing leg will be 18 units.
To find the missing length of a triangle

No, you do not need to know the length of all the sides of one triangle to find a missing length of a similar triangle. If you know at least one pair of corresponding sides from both triangles, you can use the proportionality of the sides in similar triangles to find the missing length. The ratio of the lengths of corresponding sides remains constant, allowing you to set up a proportion to solve for the unknown length.
usually its used to find a missing angle or length of a right triangle. Of course there is more to trigonometry. any way you can use sine, cosine, and tangent, to fine the missing angle or length
That will depend on the information given as for example if you are given its width and area then in order to find its length divide the width into the area.
To find the missing side length in a pair of similar figures, you can use the property that corresponding sides of similar figures are in proportion. Set up a ratio using the known side lengths from both figures, such that (\frac{\text{length of one side in figure 1}}{\text{length of corresponding side in figure 2}} = \frac{\text{missing side in figure 1}}{\text{known side in figure 2}}). Cross-multiply to solve for the missing length. Finally, simplify to get the value of the missing side.
You use the pythagorean theorem.
they are all the same length
The length of the other side is: 28.6 cm
If there is no length for the hypotenuse you have to use the Pythagorean Theorem. If there are two sides missing and a reference angle you could use Trigonometry.
The third side can be of any length in the interval (2, 128) units of length.
