Usually, you are given at least a length and an angle
Using these two known parts of a scalene triangle
Imply the sine laws
SinA/a = SinB/b = SinC/c
Where A is the angle, and a is the length
You need to know at least three parts, either two angles and a side, or two sides and an angle to find the unknown using the above pattern.
Use two out of the three equated sine equations above with your known values

It is not much help to give an answer that suggests using the sine law when it may not be of any help. The proper answer is that it will all depend on what you are given. And that is the bottom line.
You cannot assume that you are given "at least a length and an angle". You could be given two lengths and an altitude, for example. In that case the sine law would be useless. Or you could be given two sides and a median - again no help from the sine law. In any of these cases, some hard trigonometry is required before you can get to the answer.
Furthermore, if you are given two sides and the included angle, you have a, b and C or sin(C). So you cannot evaluate any of the three ratios to use the sine rule because you have only one of the two components in each ratio. Alternatively, if you have two sides and an angle other than the included angle, you have the "ambiguous case" where the triangle can have two possible shapes.
In short, I believe that the sine rule cannot help unless you have a lot more information about the triangle.

What kind of triangle has no sides of equal length?
a scalene triangle
What is the properties of a scalene triangle?
A scalene triangle is one whose sides are unequal - each side is different in length.
A triangle having three sides of different length?
I believe that is called a Scalene triangle.
What are scalene triangles?
an scalene is a triangle with no sides the same lengthas in an equilateral has sides all the same length
What triangle has all three sides unequal?
Scalene TrianglesA scalene triangle has no sides of equal length. Its angles are also all different in size.
How do you find the perimeter of a scalene triangle?
-- Find the length of one side. -- Find the length of another side. -- Find the length of the remaining side. -- Add the three numbers. -- Their sum is the perimeter of the scalene triangle.
Which triangle does not have any sides the same length?
A scalene triangle
What kind of triangle has sides of different length?
A scalene triangle.A scalene triangle.A scalene triangle.A scalene triangle.
Does a scalene triangle have no sides of the same length?
No sides of a scalene triangle are the same length.
What about the scalene triangle that makes it a scalene triangle?
A scalene triangle makes it scalene because all sides have different length.
How are isosceles triangle and a scalene triangle are different?
An isosceles triangle has two sides that are the same length. A scalene triangle does not have any sides that are the same length.
show a picture of a scalene triangle?
A Scalene Triangle is a triangle where all three sides are different in length.
Triangle in which no sides have the same length?
A scalene triangle.
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.
A triangle that has no same length?
Scalene
Can some scalene triangle are isosceles triangle?
No, because a scalene triangle is a triangle with no sides the same length. An isosceles triangle is a triangle with two sides the same length and one side different
What is an isosceles triangle and a scalene-triangle?
An isosceles triangle is when only two of the triangle's sides are equal in length. A scalene triangle is when no sides are equal in length. There is also an equilateral triangle which all of the triangle's sides are equal.
