Two triangles can be formed with the given information. Use the Law of Sines to solve the triangles.
B = 46°, a = 12, b = 11
A = 38.3°, C = 95.7°, c = 8; A = 141.7°, C = 84.3°, c = 8
A = 51.7°, C = 82.3°, c = 8; A = 128.3°, C = 5.7°, c = 8
A = 38.3°, C = 95.7°, c = 15.2; A = 141.7°, C = 84.3°, c = 15.2
A = 51.7°, C = 82.3°, c = 15.2; A = 128.3°, C = 5.7°, c = 1.5

Best ResponseYou've already chosen the best response.1that's fine :) Anyway, so the sine rule basically is this: \[\frac{ a }{ sinA } = \frac{ b }{ sinB} = \frac{ c }{ sinC} \] and you can even flip it around: \[\frac{ sinA }{ a } = \frac{ sinB }{ b}= \frac{ sinC }{ c }\] Now you want to draw up a triangle and label the information give to you which is: B = 46 , a = 12, b = 11 so, dw:1436242931550:dw Firstly, we want to find angle A

Best ResponseYou've already chosen the best response.1Using the sine rule we can find angle A like this : \[\frac{ sinA }{ a } = \frac{ sinB }{ b } \rightarrow \frac{ sinA }{ 12 } = \frac{ \sin46 }{ 11 }\]

Best ResponseYou've already chosen the best response.0A = 51.7°, C = 82.3°, c = 8; A = 128.3°, C = 5.7°, c = 8 A = 51.7°, C = 82.3°, c = 15.2; A = 128.3°, C = 5.7°, c = 1.5 so which one of these are the answers? @butterflydreamer

Best ResponseYou've already chosen the best response.1yeeep so A = 51.7 Now use the sine rule and follow a similar method to solve for c and C

Best ResponseYou've already chosen the best response.1dw:1436244696917:dw Find angle C by using the fact that the angle sum (all 3 angles in a triangle) = 180. So we have two angles right? A = 51.7 , B = 46. Therefore C = 180  51.7  46 = ?

Best ResponseYou've already chosen the best response.1yeep C = 82.3 Now to find the length of c, we need to use the sine rule again: dw:1436244903292:dw dw:1436244943797:dw
