OR, (lol), use the Pythagorean theorem, e.g.:
a2+b2=c2
Let A be one leg (short side), B the other leg, and C the hypotenuse (long side).
So if the measurements of the two short sides (a and b) are say, 3 and 4 , then you do:
3*3=9
4*4=16
therefore
9+16=c2
So then, it is: 25=c2
Assuming one already knows basic algebra, take the square root of both sides of the equation to get:
(square root of 25)=(square root of 'c')2
And since the square root of C squared is simply C, we know that C is equal to the square root of 25, which is 5.
Therefore, the missing side (C) is 5 units. Knowing algebra you can use the same equation to find any side (with any given side lengths), but C is the most common in math books.

How do you find the missing area measurement of a triangle?
depends on the needed measurement and type of triangle.
How do i find the' missing measurement on a triangle that has a base of 20 and an area of 30ft2?
The depends on what the missing measurement is. From here, I can see at leastthree missing measurements . . . the height of the triangle, and the lengths of theother two sides. The method needed in order to find the 'missing measurement'depends entirely on which one of those you're asked to find.Here's a formula that may come in handy. If not, just put it away for later.Area of a triangle = 1/2 (Base times Height)
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.
How do you find a 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.

What does Pythagoras famous theroem involve?
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.
How can you find a missing side or angle of a right triangle?
180 minus two known angle = missing angle. Use Pythagoras' theorem to find its missing side.

How do you use sine cosine and tangent?
They are used to find the angle or side measurement of a right triangle. For example, if 2 sides of a right triangle have known values and an angle has a known measurement, you can find the third side by using sine, cosine or tangent.
How do you find the missing side from a right triangle?
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.
How do you find a missing side to a right triangle?
A triangle always has 180 units. You would have to add up the two sides and subtract that from 180.
How do you find the missing measurement in a paralellagram?
It depends on what measure is missing.
How do you find a missing side on a triangle?
If you have at least 2 of the angle measurements and are trying to find the measurement of a missing angle you should do this: When you have the measurement of two angles, add them together. Then subtract the total from 180(always the sum of all of the triangle's angle's measurements). It will give you the measurement of the missing angle. If you are trying to find the length of the missing side, then use the Pythagorean theorem (a squared+b squared=c squared, c being the missing side) THIS ONLY WORKS FOR RIGHT TRIANGLES, however. first of all this didnt help me. second that therom is stupid cuz im only in 8th grade integrated algebra! get me a good answer jeez. i need to find the missing lenngth help me someone ---------------------------------------------------------------------- Honey, the thereom is the only way to get the right answer. And I'm in 7th grade, so get over the "you're only in 8th grade" I'm in 7th grade and understood what he said. I'd suggest using the answer he gave, 'cause that's the best you can get.
