We can use pythagoras' theorem to solve this. Make the shortest side, (A), the next longest side (B) and the longest side (C). Then square all the measurements : A2 + B2 = C2. So the length of C will be given to you in a squared number, so simply use the square root of that number for the length. You can then rearrange the formula to get the length of the side you want, if you're not looking for C.

∙ 15y agoOne side is not enough. For a right triangle the third side can be calculated by Pythagoras' Theorem if you know the length of any two sides.
If the length of only one side is known, it is not possible to determine whether or not the triangle is right angled.
You can do it only of the triangle is right angled and if one of its legs is the same length as the side of the square. In that case, let that side of the triangle abut a side of the square.
In an isosceles triangle, two sides are of equal length. An isosceles triangle also has two congruent angles. An equilateral triangle is an isosceles triangle, but not all isosceles triangles are equilateral triangles. __________ A right triangle (or right-angled triangle, formerly called a rectangled triangle) has one 90° internal angle (a right angle). The side opposite to the right angle is the hypotenuse; it is the longest side in the right triangle. An isoceles triangle has TWO sides of equal length but and equilateral triangle has THREE sides of equal length.

There is not enough information to solve this. You need to know one other length od a side to solve this.
Assuming that you are talking about a right triangle. a2 + b2 = c2 Solve for a a = square root of c2-b2
By using the formula a2+b2=c2, where a is one side of the right-angled triangle and b is the other side of the right angle triangle. C stands for the hypotenuse of the right-angled triangle. Note: this formula only works for RIGHT-ANGLED TRIANGLES!!!
I don't think there is enough information to answer the question, first of all, is it a right triangle? Second, is the the 13cm the hypotenuse. Assuming that 13cm is the hypotenuse, and the triangle is a right triangle, the equation would be 49+x^2=169
It cannot be determined from the available information.
You cannot find any angle, or either of the other two sides, in a non-right triangle, when given only one side.
