Let the sides be a b c and their opposite angles being A B C and so:-
3rd angle: 180-73-59 = 48 degrees
Using the sine rule the length of side b = 13.8 cm
Using the sine rule the length of side c = 15.4 cm
The largest angle will be opposite length 8cm and by using the cosine rule it works out as 125.1 degrees rounded to one decimal place
All triangles have 3 sides and 3 interior angles that add up to 180 degrees. If you know the lengths of 2 sides of a triangle then the length of the 3rd side can be found by using trigonometry.
An EQUILATERAL triangle has all three sides the same length. An ISOSCELES triangle has two sides with the same length. A SCALENE triangle has all three sides different lengths.
The length of the hypotenuse of a right triangle with legs of lengths 6 and 8 inches is: 10 inches.
You require another piece of information. Knowing the "vertex" angle will not tell you the length of any one side. You can have a triangle the size of the continental USA with a "vertex" angle of 15 degrees and you can have a triangle invisible to the human eye with a "vertex" angle of 15 degrees. You can see how these would have different side lengths.
A triangle that has two sides of equal length. Sometimes it is specified as having two and only two sides of equal length, and sometimes as having at least two sides of equal length
The largest angle will be opposite length 8cm and by using the cosine rule it works out as 125.1 degrees rounded to one decimal place
The length of the hypotenuse of a right triangle with legs of lengths 5 and 12 units is: 13The length of a hypotenuse of a right triangle with legs with lengths of 5 and 12 is: 13
A triangle with no equal side lengths is a scalene triangle.
All triangles have 3 sides and 3 interior angles that add up to 180 degrees. If you know the lengths of 2 sides of a triangle then the length of the 3rd side can be found by using trigonometry.
An EQUILATERAL triangle has all three sides the same length. An ISOSCELES triangle has two sides with the same length. A SCALENE triangle has all three sides different lengths.
The length of the hypotenuse of a right triangle with legs of lengths 6 and 8 inches is: 10 inches.
The lengths of a scalene triangle are of 3 different sizes and it also has 3 different interior angles that add up to 180 degrees.
You require another piece of information. Knowing the "vertex" angle will not tell you the length of any one side. You can have a triangle the size of the continental USA with a "vertex" angle of 15 degrees and you can have a triangle invisible to the human eye with a "vertex" angle of 15 degrees. You can see how these would have different side lengths.
A triangle with 2 equal side lengths is called an isosceles triangle.
The lengths of the legs of a right triangle are 15 cm and 20 cm. What is the length of the hypotenuse?
If the lengths of its 3 sides are equal then it is an equilateral triangle.
