Step-by-step explanation:
Given
2cosΘ - = 0 ( add to both sides )
2cosΘ = ( divide both sides by 2 )
cosΘ =
Since cosΘ > 0 then Θ is in first and fourth quadrants, hence
Θ = ( ) =
OR
Θ = 2π - =
solutions are Θ = ,
If c is not zero then b÷c =
From the problem we have
In △ABC, m∠A=52°, c=11, and m∠B=19°.
Draw the diagram with the help of given information, (see the attached image)
Now using Sine Law in the Triangle ABC, we can write
Now from Triangle ABC , we can write
Now simplify , we get
