a.
Explanation of Solution
Given information:
Refer to the figure. If
Calculation:
Here, we know that according to law of sines:
Now, as a triangle whose angles are
Now, for
Now, we will subtract
Here, we will find side
Now, substitute
As, we know that
Now, we will multiply both sides of the equation,
Here we will find the area of the triangle
Put
Hence, the area of
b.
