What is the length of the third side of a scalene triangle that has two sides of 2.8 cm and 6.2 cm with an angle of 100 degrees between them?

Let the third side be "a" and use the cosine rule to find the third side:
a2 = (2.82+6.22)-2*2.8*6.2*cos100o
a2 = 52.309066473
Square root both sides:
a = 7.232500586
Length of the third side = 7.23 cm to two decimal places.

Does a scalene triangle have no sides of the same length?
No sides of a scalene triangle are the same length.
What kind of triangle has sides of different length?
A scalene triangle.A scalene triangle.A scalene triangle.A scalene triangle.
What about the scalene triangle that makes it a scalene triangle?
A scalene triangle makes it scalene because all sides have different length.
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.
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.
Which triangle does not have any sides the same length?

What triangle has 57 degrees 88 degrees and 35 degrees?
It could be described as an acute triangle since each angle is less than 90 degrees. Each angle is different, and the same for length of sides, so this could also be called a scalene triangle. It's an acute scalene triangle.
What is the difference between a isosocels and a scalene triangle?
A isosceles triangles has two sides of equal length while a scalene has none of equal 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.
What is the difference isosceles triangle and a scalene?
An isosceles triangle has two (or more) sides of equal length, while a scalene triangle has no correlation between side lengths/angle size.
show a picture of a scalene triangle?
A Scalene Triangle is a triangle where all three sides are different in length.
How are equilateral triangles and scalene triangles different?
In an equilateral triangle, all three sides are of the same length and all three angles are the same measure (60 degrees). In a scalene triangle, all three sides are of different length and all three angles are ofdifferentmeasure.
Triangle in which no sides have the same length?
A scalene triangle.
