if one side of a triangle is 5ft and the other is 13ft .what is the last sides lenght in feet?

Answer 1

You would need some more parameters to know for sure. For example, is it a right triangle? If not, do you have any angle measures? And if it is a right triangle, are these the measure of the legs, or is one a hypotenuse?

A common Pythagorean triple is 5-12-13, meaning a right triangle has legs of 5 and 12 and a hypotenuse of 13. I suspect the question is for this triangle where a = 5, c = 13.

a² + b² = c²
5² + b² = 13²
25 + b² = 169
b² = 144
b = sqrt(144) = 12 ft.

Answer 2

If it is a right angle triangle then :

( Base )^2 + ( Perp )^2 = (Hypotenuse )^2

Here these two sides are either base and Perp. or Base or perp and hyp.
Therefore.
Case :I 5^2 + 13 ^2 = H^2

or 25 +169 =H^2

or H = (194 )^1/2
or H = Approx.14

Case II : 13^2 = 5^2 + P^2

or P^2 =169-25

or P^2 =144
or P=12
So the third side is either 12 or 14.

Answer 3

If Its a Right Triangle
other side = 12 ft

Any other triangle
You need to give any other measurement

Answer 4

um. . . . .not possible. You haven't provided enough information.

Answer 5

you need to provide us with either angle measures, or information as to if it is a right angle or not. if it is a right triangle, then you can do the pygathorean theorem which is a^2+b^2=c^2 with a and b being the two legs and c being the hypotenuse (Longest side)

Answer 6

I can only answer this question if the two side mentioned are the leg and the hypotenuse; the side asked for is the other leg; and if this is a right triangle.

If so, using the formula a^2+b^2=c^2, which in this case b^2 is equivalent to the side asked for, we have the equation

13^2-5^2=c^2
169-25=144

the sq. root of 144 is 12, so the answer is 12 ft.

Answer 7

not enough info.

either 13.928388 or 12

Answer 8

Not enough information.

Answer 9

You did not give enough information. To answer this question, you need at least one angle.

If it is a right triangle and 13 is the length of the hypotenuse and 5 is the length of one of the legs, then you can use pythagorean theorem.

5^2 + x^2 = 13^2

Solving, you get x = 12.

If it is a right triangle and 5 and 13 both represent lengths of legs, then you can use Pythagorean's theorem again.

5^2 + 13^2 = x^2

Solving, you get x = 13.9284

If it is not a right triangle you can use other techniques such as Law of Sines and Law of Cosines.

Conclusion: If you want an answer, please provide more information.

Answer 10

You haven't given enough information to solve this, because it depends on the angle between those two sides.

The only thing you can say about the length of the other side is that, if its length in feet is x, then:

0 < x < 18
