What else can I help you with?
When given all three side lengths of a triangle but none of the angle measures you can solve for all angle measures using?
With trigonometry by using the cosine rule
What is the angle-angle-side rule?
Side-Angle-Side is a rule used in geometry to prove triangles congruent. The rule states that if two sides and the included angle are congruent to two sides and the included angle of a second triangle, the two triangles are congruent. An included angle is an angle created by two sides of a triangle.
What is the largest angle of a triangle with sides of 14 cm 8.5 cm and 9 cm?
The largest angle of the triangle will be opposite its largest side and by using the Cosine Rule it works out as 106.23 degrees.
What is the length of the third side of a triangle when the other sides are 17 cm in length with an angle of 45 degrees between them?
Using the cosine rule: 13.0112367 cm The triangle is in fact an isosceles triangle.
What is the smallest angle of a triangle with sides of 6.4 cm 8.2 cm and 5.7 cm?
The smallest angle will be opposite the smallest side of the triangle and so by using the cosine rule it works out as 43.84 degrees.

Where does Pythagoras's rule not work?
Pythagoras's Rule does not work if the triangle is not a right angle triangle, that is having one angle equal to 90 degrees. (The rule can still be applied by creating right angles along one or more sides, using lines perpendicular to the side.)
What is the biggest angle of a triangle that has sides of 9cm by 14cm by 8.5cm?
By using the cosine rule in trigonometry the biggest angle works out as 106.23 degrees.

If the only information given about an oblique triangle is the lengths of the three sides which method should you use to solve for the angles?
By using the cosine rule in trigonometry the angles of the triangle can be worked out.
What is the smallest angle of a triangle with sides of 6.4 cm 8.2 cm and 5.7 cm?
The smallest angle will be opposite the smallest side of the triangle and so by using the cosine rule it works out as 43.84 degrees.
How do you decide angle of a triangle using cosine rule?
If the lengths of the three sides are a, b and c units, then the angle opposite side a, that is, angle A is given by cos-1[b2 + c2 - a2)/(2bc)]
How many angle of a triangle?
there are 3 angles in a triangle which is mathematically true if you check in the math rule book and rule determined by Andres Schavascapel
An isoceles triangle has two sides of 52 and one side of 40 What are the angles?
Let the sides be abc and their opposite angles be ABC and so: Using the cosine rule angle A = 67.38 degrees Using the cosine rule angle B = 67.38 degrees Angle C: 180-67.38-67.38 = 45.24 degrees
