Suppose a triangle has two sides of length 33 and 37 that the angle between these two sides is 120 What is the length third side of the triangle?
Using the cosine rule the 3rd side works out as 60.655 rounded to 3 decimal places
How do you find the length of third side of a triangle given two sides and permeter of the triangle?
Subtract the two side lengths from the perimeter. The perimeter of a triangle is just the length of the 3 sides added together. Eg. Q: A triangle has a perimeter of 20 m. One side is 5m and another is 10m. How long is the 3rd side? A: Perimeter - side 1 - side 2 = side 3 Side 3 = 20 - 5 - 10 = 5 m
If a line divides 2 sides of a triangle proportsonality then what is it to the 3rd side?
Parallel
How do you find values for the third side of a triangle?
Perimeter -2 known sides = 3rd side 180 -2 known angles = 3rd angle
What is the length of bc in the right triangle 26 10?
Use Pythagoras' theorem to find the 3rd side
Can 9.2 14.5 17.1 be the lengths of the sides of a triangle?
Yes check: the sum of the two length sides > the 3rd length side the difference of the two length sides < the 3rd length side
Suppose a triangle has two sides of length 33 and 37 that the angle between these two sides is 120 What is the length third side of the triangle?

How do you solve for triangle side lengths?
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.
What is the length of altitude drawn to the hypotenuse of a triangle with given sides of 7 and 21?
If it's a right angle triangle then use Pythagoras' theorem to find the 3rd side

What is the perimeter of 14 inches wide and 24 inches long on a triangle?
That would depend on the length of the 3rd side but in general the perimeter of any triangle is the sum of its 3 sides
How do you use the altitude to find the length of a right angle?
If 2 sides are known then use Pythagoras' theorem to find the 3rd side of a right angle triangle.
If a line divides 2 sides of a triangle proportsonality then what is it to the 3rd side?

If I have the measurement of 2 sides of a triangle and I need the measurement of the 3rd side with a 90 degree angle?
The 3rd side of the right angle triangle can be found by using Pythagoras' theorem.
What is the length of the 3rd side of a triangle having sides of 17.1cm and 28.8cm whose opposite angles add up to 72 degrees?
The largest angle then is 108 degrees that is opposite the 3rd side which is the longest side and by using the cosine rule in trigonometry it is 37.77cm in length rounded to two decimal places
What is the length of side c if the long side is 8ft and the 3rd side is 4ft?
Is this a right triangle or what? You need more information.
How do you find values for the third side of a triangle?
Perimeter -2 known sides = 3rd side 180 -2 known angles = 3rd angle
