**Solving triangles the sine and cosine rules**

3/08/2014 · Best Answer: All the angles in your solution are acute and it asks for one to be *obtuse*. When you have SSA (Side, Side, Angle) you can have two solutions (ambiguous case).... A large range of presentations and activities showing learners how to find missing lengths and angles of triangles by using the sine and cosine rule.

**The Law of Sines The Sine Rule The Sine Rule Formula**

Written as a formula. The Law of Sines is written formally as where A is the So if we are given one side and its opposite angle we can find the "law of Sines" ratio for the triangle. Then, using that ratio and the other given elements, we can solve the triangle. Proof See Proof of the Law of Sines. Things to try In the figure above click "hide details' then reshape the triangle by dragging... The Sine Rule - The Sine Rule C. McMinn SOH/CAH/TOA can only be used for right-angled triangles.

## How To Find Obtuse Angles In Triangles Using Sine Rule

### To find the other two angles, we use the sine rule to find one of them and then subtract the sum of the other two angles from 180° to find the third. The reason for using the longest side first is to prevent ambiguous results when using the sine rule.

- The law of sines can be used to find missing angle or side measurements on a triangle. You can use this quiz to test your skill level in utilizing the law of sines and finding missing information
- 22/01/2009 · How do you work out an obtuse angle in a triangle using the sine rule? When you have two of the sides and one angle. Follow . 3 If the triangle does not have an obtuse angle, you can't "work it out". Let a be one side and b another side and A be the angle opposite a. Then a/sinA = b/sinB So you can now solve for the angle B. Then angle C = 180 -A-B. ironduke8159 · 1 decade ago . 0. …
- In trigonometry, the law of sines, sine law, sine formula, or sine rule is an equation relating the lengths of the sides of a triangle (any shape) to the sines of its angles…
