You can use the Law of Sines to solve real-life problems involving oblique triangles. ]]> 2016-05-18 00:19:18 UTC https://padlet.com/melxmel99/r8sv2nf7qhdf/wish/111356286 melxmel99 https://padlet.com/melxmel99/r8sv2nf7qhdf/wish/111599576 Oblique triangles: triangle that have no right angles. 
For example:  ]]> 2016-05-19 06:56:07 UTC https://padlet.com/melxmel99/r8sv2nf7qhdf/wish/111599576 melxmel99 https://padlet.com/melxmel99/r8sv2nf7qhdf/wish/111600052 To solve an oblique triangle you need to know the measure of at least one side and any other parts of the triangle. 
Types you can solve:
•2 sides amd any angle. (AAS or ASA)
•2 sides and an angle opposite one of them.

You can use either one depending what you are trying to fine.]]> 2016-05-19 07:04:38 UTC https://padlet.com/melxmel99/r8sv2nf7qhdf/wish/111600792 melxmel99 https://padlet.com/melxmel99/r8sv2nf7qhdf/wish/111601292 Let's refer to the second triangle on "Knowing the types of triangles". I will show you how to solve step by step.
•This triangle is an SAS.
•The given sides are a=55 and c=20. The given angle is sin110.
•First thing you will do is write down formula replacing its' variables with its given numbers.
• (the B at the top is supposed to be b)]]> 2016-05-19 07:08:15 UTC https://padlet.com/melxmel99/r8sv2nf7qhdf/wish/111601292 melxmel99 https://padlet.com/melxmel99/r8sv2nf7qhdf/wish/111602506 •circle the ones that can be solved
•Because they all equal each other it does not matter which one you pick as long as it can be solved. 
•i picked those too because you only had to find one angle and it is not possible to find sin B without its side.

Because it is not easy to solve it in this way, we will flip the equation to make it look like this:]]> 2016-05-19 07:20:03 UTC https://padlet.com/melxmel99/r8sv2nf7qhdf/wish/111602987 melxmel99 https://padlet.com/melxmel99/r8sv2nf7qhdf/wish/111603741 •Get the angle you are trying to find on one side. So multiply 20 on both sides.
•put in your calculator: 20(sin110/55)
•your answer will be 0.34.
•you will get C alone so you will have to get the opposite of sin and mulitply that by 0.34.
•you find the angle C as 19.88.]]> 2016-05-19 07:25:43 UTC https://padlet.com/melxmel99/r8sv2nf7qhdf/wish/111603741 melxmel99 https://padlet.com/melxmel99/r8sv2nf7qhdf/wish/111604327 •so you know angle A=110 and angle C= 19.88.
•a triangle always adds up to 180.
•just subtract 110 and 19.88 by 180 and you find angle B.
