If you mean angle A is 54 degrees and side b is 13 and side c is 9 then by using the cosine rule in trigonometry side 'a' which is the 3rd side works out as 10.605 units rounded to three decimal places.
If the hypotenuse is equal to 7 and one side is equal to 4, the third side is: 5.745
40 degrees
The minimum third side length of a triangle having one side of 11 and another side of 5 is 6.
The third side would be either 5 or 8,as an isosceles triangle has 2 equal sides.
if the equal sides of an isosceles triangle have lengths a, and the third side is 12 in., find a
in an isosceles triangle one of its size is not equal to the other two sides, that is 2 of its sides are equal to each other except the third side.
The Pythagorean Theorem.
It says the sum of the lengths of any 2 sides of a triangle must be greater than the third side. Not equal to but GREATER than the third side.
in which the sum of two sides less than or equal to the third side.
An isosceles triangle has 3 sides 2 of which are equal in length
no it can not be eaual but it can be greater than The sum of the lengths of any two sides of a triangle is greater than the length of the third side.
Sounds like an isosceles triangle, with the line of symmetry from the third angle to the mid-point of the third side.
