In order to apply the law of cosines to find the measure of an interior angle it is enough to know which of the following the measure of an interior angle i?
To apply the law of cosines to find the measure of an interior angle in a triangle, you need to know the lengths of all three sides of the triangle. Specifically, if you have sides ( a ), ( b ), and ( c ), you can use the formula ( c^2 = a^2 + b^2 - 2ab \cos(C) ) to solve for the angle ( C ). Thus, knowing the side lengths is sufficient to determine the interior angle.
How do you find the values of variables on a triangle?
To find the values of variables in a triangle, you can use various properties and theorems such as the Triangle Sum Theorem, which states that the sum of the interior angles of a triangle is always 180 degrees. If you have the lengths of the sides, you can apply the Law of Sines or the Law of Cosines to find unknown angles or sides. Additionally, if the triangle has specific characteristics (like being right-angled or isosceles), you can use those properties to simplify your calculations. Always ensure you have enough known values to set up equations for the unknowns.
How do you find the hypotenuse of a triangle when the length of the legs are 10?
That's a perfect time to recall and apply the Pythagorean Theorem:C2 = A2 + B2There is absolutely no finer way to find the length of the hypotenusewhen you know the length of the legs.

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.
How do you calculate the length of the sides of a right angle triangle when angles are known?
You need to know at least one side......after that you can use the angles to apply the equations, SOH CAH TOA.
What information is needed to apply Pythagoras Theorem?
Pythagoras theorem simply tells you the length of a side of a Right Angled Triangle if the other two sides are given. You only need the length of any two sides to calculate the length of the third onePythagoras theorem:Hypotenuse2 = base2 + perpendicular2

If the two legs of a right triangle are 6 and 13 units long what is the triangle's area?
39 sq. unitsThe area of any right triangle is A = 1/2 (b x h)1/2 (base) multiplied by (height)A right triangle can always be set down so that the legs are the base and the height.So if you know the length of the legs, you can apply the area formula directly.
