pythagorean therom add them both together and subtract from 180
vv LAW OF COSINE vv
a^2 = b^2 + c^2 - 2(b)(c)CosA
Other Answer
1) If you have a perimeter you can subtract the first two from the total perimeter.
2) If it is a right triangle and you are missing the hypotenuse (the slanted one), the formula a^2 + b^2 = c^2 is used. (Words-- A squared plus B squared equals C squared.)
(A) is the length that is upright, (B) is the length that is sideways, and (C) is the hypotenuse, or the answer.
If you have a right triangle you can work that question backwards.

they are all the same length
The length of the other side is: 28.6 cm
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
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.
The sine function is used in trigonometric calculations when attempting to find missing side lengths of a right triangle. The sine of an angle in a triangle is equal to the length of the side opposite of that angle divided by the length of the hypotenuse of the triangle. Using this fact you can calculate the length of the hypotenuse if you know an angle measure and the length of one leg of the triangle. You can also calculate the length of a leg of the triangle if you know an angle measure and the length of the hypotenuse.
To find the missing length of a triangle
You use the pythagorean theorem.

It involves a right triangle. If a length is missing in a right triangle, you can find it out by using the other two lengths.

The third side can be of any length in the interval (2, 128) units of length.

It is the same length as the corresponding side on the other triangle.
....It can help us find the length of the "HYPOTENUSE" easier.....The Pythagorian Theorem is used to find the missing length of one side of a triangle. A^2 + B^2 = C^2
It depends on what measure is missing.
