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.

How do you find the missing measurements of a triangle if you only know one side?
they are all the same length
Find the missing length for a right triangle where the short side is 9 cm and the hypotenuse is 30cm?
The length of the other side is: 28.6 cm
What do you do in trigonometry?
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
How do you find the length to a missing side of a right triangle?
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.
What is one way to find the missing side length?
One way to find a missing side length of a triangle is to use the Pythagorean theorem, which states that in a right triangle, the square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the other two sides (a² + b² = c²). If you know the lengths of two sides, you can rearrange the formula to solve for the missing side. For example, if you have the lengths of the two legs (a and b), you can find the hypotenuse (c) by calculating c = √(a² + b²).
