A triangle has two sides of lengths 5 and 13. What value could the length of the third side be Check all that apply?

A triangle has two sides of lengths 4 and 15. What value could the length of the third side be Check all that apply.?
It could be 12 because the sum of the 2 smaller sides of a triangle must be bigger than its largest side.
What is the length of the hypotenuse of a right triangle with legs of lengths 6 and 8?
Being a right-triangle, apply Pythagoras. Hence h^(2) = a^(2) + b^(2) Substitute h^(2) = 6^(2) + 8^(2) h^(2) = 36 + 64 h^(2) = 100 Square root BOTH sides. h = 10 (The length of the hypotenuse.
Can 18 24 30 be the side lengths of a right triangle?
YES. 18 and 24 are the two leg lengths and 30 is the hypotenuse then by Pythagoras' Theorem :- 182 + 242 = 302 324 + 576 = 900......which is true and therefore the three side lengths 18, 24 and 30 do form the sides of a right-angled triangle.
How do you find the cosine of a triangle?
For the length you apply this formula, after numbering the sides a²=b²+c²-2bcCosA

Can a triangle have side lengths 6 8 and 9?
Yes, a triangle can have side lengths of 6, 8, and 9. To determine if these lengths can form a triangle, we can apply the triangle inequality theorem, which states that the sum of the lengths of any two sides must be greater than the length of the third side. In this case, 6 + 8 > 9, 6 + 9 > 8, and 8 + 9 > 6 all hold true, confirming that a triangle can indeed be formed with these side lengths.
Is the following shape a right triangle?
To determine if a shape is a right triangle, you need to check if one of its angles measures 90 degrees. Alternatively, you can apply the Pythagorean theorem, which states that in a right triangle, the square of the length of the hypotenuse equals the sum of the squares of the lengths of the other two sides (a² + b² = c²). If either condition is met, then the shape is a right triangle.
Could segments 9415 form a triangle?
To determine if segments 9415 can form a triangle, we can apply the triangle inequality theorem, which states that the sum of the lengths of any two sides must be greater than the length of the third side. If we let the segments represent the lengths a = 9415, b = 9415, and c = 9415, we can check the conditions: a + b > c, a + c > b, and b + c > a. Since 9415 + 9415 > 9415 holds true, the segments can indeed form a triangle.
What triangle has side lengths that are 3 cm 4 cm and 6 cm?
The triangle with side lengths of 3 cm, 4 cm, and 6 cm is a scalene triangle, as all three sides have different lengths. To determine if it forms a valid triangle, we can apply the triangle inequality theorem, which states that the sum of the lengths of any two sides must be greater than the length of the third side. In this case, 3 + 4 > 6, 3 + 6 > 4, and 4 + 6 > 3 are all satisfied, confirming that these sides can indeed form a triangle.
What is the length of the hypotenuse of a right triangle with legs of lengths 6 and 8?
Being a right-triangle, apply Pythagoras. Hence h^(2) = a^(2) + b^(2) Substitute h^(2) = 6^(2) + 8^(2) h^(2) = 36 + 64 h^(2) = 100 Square root BOTH sides. h = 10 (The length of the hypotenuse.
What is the length of missing side B in the figure of a triangle with one side 7 cm and one side 13 cm?
To determine the length of the missing side B in a triangle, we need more information about the triangle, such as whether it is a right triangle or the length of the third side. If the triangle is a right triangle, we could apply the Pythagorean theorem. If it's not a right triangle, we would need the measure of the included angle or additional side lengths to make a calculation. Without this information, the length of side B cannot be determined.
What is the length of EF in the right triangle?
To determine the length of EF in a right triangle, you would typically need the lengths of the other two sides or some angles. If EF represents one of the sides of the triangle, you could apply the Pythagorean theorem (a² + b² = c²) if the lengths of the other two sides are known. Alternatively, if EF is a segment related to the triangle's angles, trigonometric ratios could be used. Without specific measurements or additional details, it's not possible to provide a numerical answer.
How do you calculate angles in a scalene triangle?
If you know the lengths of the sides, you can use the cosine rule. If you have information about other aspects of the triangle, then other formulae will apply.
If l 12 cm and m 35 cm what is the length of n?
To determine the length of ( n ), we need more context about the relationship between ( l ), ( m ), and ( n ). For example, if they are the sides of a triangle, we would need to apply the triangle inequality. If they represent lengths in a different context (e.g., segments of a line), please provide additional details.
Can 18 24 30 be the side lengths of a right triangle?
YES. 18 and 24 are the two leg lengths and 30 is the hypotenuse then by Pythagoras' Theorem :- 182 + 242 = 302 324 + 576 = 900......which is true and therefore the three side lengths 18, 24 and 30 do form the sides of a right-angled triangle.
