If you have angles, use the sine rule:
a/sin A = b/sin B = c/sin C
a denotes the side, A the angle opposite the side.

What is the length of the third side of an equilateral triangle have?
The length of the third side of an equilateral triangle is the same as the lengths of both of the other two sides.
Can A scalene triangle can have a right angle?
I believe a scalene triangle CAN have a right angle. Def of scalene tri: a triangle with no equal sides, and no equal angles. A triangle with angles of 90, 29, and 61. Sides of 15.0, 27.0, and 30.9 this satisfies the definition. If you look at it the other way: can a right triangle be non-scalene, and there is only one possibility: the isosceles right triangle (45°, 45°, 90°), with sides (square_root(2), 1, and 1). It's not possible for an equilateral triangle to have a right angle. So all other right triangles are scalene (but not all scalene triangles are right triangles).
Two types of triangle?
There are three main types of triangle:Scalene - all angles are different and all sides are different lengthsIsosceles - Two sides are equal in length and the two angles (between the third side and the two sides of equal length) are equalEquilateral - All three angles are equal (at 60°) and all three sides are of equal length.If all angles are less than 90° then the triangle can also be described as an Acute triangle; an equilateral triangle is acute by definition as all angles are 60° which is less than 90°.A Scalene or Isosceles triangle can also be described as a Right angle triangle if one angle is 90° (a right angle); in the isosceles triangle this is the angle between the sides of equal length.A Scalene or Isosceles triangle can also be described as an Obtuse triangle if one angle is greater than 90°; in the isosceles triangle this is the angle between the sides of equal length.
What is the length of EF in the triangle below with legs of 39 and 15?
Since there is no triangle "below", all that can be said is that EF - if it is the third side of the triangle - is any length in the interval (24, 54).
What is the area of a triangle 4cm by 8cm?
It depends on the length of the third side.
What is the difference between an scalene right triangle and a scalene obtuse triangle?
A scalene triangle is a triangle in which all three sides have different lengths. The difference between a scalene right triangle and a scalene obtuse triangle is that in the first one, we can find the measure length of the third side when we know the lengths of the two other sides, and in the second one we cannot.
Which triangle angle measures 32 degrees 79 degrees and 69 degrees?
What is a 79 degree of a third angle of a triangle
What is a triangle with angle of 37 degree's and 75 degree's?
The third angle is 68 degrees which makes it a scalene triangle
What type of triangle is 28 degrees and 110 degrees?
As the third angle must be 42 degrees, it is a scalene triangle.
What triangle isangle 50 and angle 70?
The third angle must be 60 degrees so it is a scalene triangle
An isoscles triangle is a triangle that has?
An isoceles triangle is a triangle which has exactly two sides of equal length. The third side can be longer or shorter than the other two. The two sides being of equal length means that two of the angles are of equal size (not the one between the two equal-sized sides).Other types of triangleAn equilateral triangle is one where all three sides are of equal length and so all angles are of equal size. A right-angled triangle is one which has a right angle in it. It can be either an isoceles triangle or a scalene triangle. Scalene triangles are triangles where every side is of a different length and every angle is of a different size.
How do you find the third angle of a scalene triangle?
If you have the other two angles, you can subract them from 180 degrees, which is the sum of the angles in any triangle.
What is the length of the third side of an equilateral triangle have?
The length of the third side of an equilateral triangle is the same as the lengths of both of the other two sides.
What kind of triangle has two sides with length 15 and one side with length 25?
isoscelesAs regard their sides, triangles may beScaleneIsoscelesEquilateralAnd in regard to their angles, triangles may beAcuteRightObtuseEquiangularA triangle is scalene if all of its three sides are 'different'.If only two of its sides are equal, the triangle is called isosceles.A triangle with all three 'equal' sides is called equilateral.So, a triangle with a length of 15 on two sides and a length of 25 on the third side would be Isosceles, since two of the sides are the same.
If two sides of a triangle equal 45 what does the third equal and what kind of triangle is this?
If two sides of a triangle each have length of 45 units, then the triangle is isosceles,and the third side can have any length less than 90 units.
What is formula of finding the perimeter of a triangle?
Perimeter of a triangle = (length of the first side) plus (length of the second side) plus (length of the third side)
What is the measure of the third side of an equiteral triangle have?
The length of the third side is the same as the length of either of the other two sides.
