Find the missing side of a triangle?

Question

if one long side is 12 and the base is 5 what is the other long side

Answer 1

Well, if you're in Geometry, you can simply remember that 5, 12, 13 is a Pythagorean triple. (Just like 3, 4, 5)
If you don't want to memorize those things, you can simply use the Pythagorean theorem. (a^2 + b^2 = c^2)
In this case, a=5, b=12, and c is your hypotenuse (unknown).
So... (5)^2 + (12)^2= (x)^2
25+144=169
13 x 13= 169
Therefore, your answer is 13!

To find a missing length of a right triangle, you use Pythagorean's Theorem: a² + b² = c² (where 'c' is the hypotenuse, or longest side) 15² + 20² = c² 225 + 400 = c² 625 = c² c = 25 *** Therefore, the missing side of the triangle is 25. * Keep in mind that this works on ONLY right triangles.

Answer 3

This question is inherently impossible, but if it is a right triangle, then it the missing side is 13 due to the equation a^2 + b^2 = c^2. 5 squared (25) plus 12 squared (144) = 169. The squareroot of 169 is 13. This side would be the hypotenuse. It is the longest side. This is a common right triangle (5, 12, 13). Hope that helps!

RE:

Answer 5

well...if the hypothenue is 12 and the 5 is the base then heres what u do:

12^2 (12 square) = 5square + b square
then just solve from there like this:

144 = 25 + b square
-25 -25
119 = b square
then get the square from oth side
the answer should be square root of 119
well u could simplify it

i dont now y this triangle has a square root of 119

but heres the thing if the 12 is not the hypotheues then
using a^2 + b^2 = c^2 (like the equation i showed u above)
then the answer would be 13

just try it

Answer 6

Your description is rather vague...

If you have a right triangle and 12 is the hypotenuse, then the square root of 119 would be the length of the remaining leg.

If it is a right triangle and 12 and 5 are legs, then the hypotenuse/remaining side would be 13. (5-12-13 triangle)

If it's not a right triangle, then whatever follows the triangle inequality theorem.

Answer 7

The other side is not at your place?

The other side is a line segment connecting
the terminii of the other two segments.

There are an infinite number of such line segements of different lengths unless
one specifies that the angle made by the line segments is fixed.
Then you can find the length of the
third. Specify a 90 degree, pi/2 radian, or
right angle and you have sqrt(144-25).

Answer 8

a2+b2=c2

a and b are the legs
c is the hypotenuse

5`2+b`2=12`2
25+b`2=144
144-25=b2
b2=119
sqrt of 119
~10.90

Answer 9

Diablo's answer will only work with a right triangle and ONLY if you specify which side is opposite the right angle. I must agree with most of your responders and say that without additional assistance on this problem, we can not solve it.. PS I used to teach math.

Answer 10

You need to know one of the angles within the triangle. Unless it is a specific type of a triangle. Ie., if it is a right angle triangle the formula would be "A squared plus B squared = C squared".
