Answer:
A is about 37.6 degrees
B is about 38.4 degrees
a is about 15.7 units
Step-by-step explanation:
Using the law of sines, you know that:
[tex]\dfrac{\sin 104}{25}=\dfrac{\sin B}{16}[/tex]
[tex]B\approx 38.4^{\circ}[/tex]
Since all of the angles of a triangle add up to 180 degrees, angle A must be 180-104-38.4=37.6 degrees.
Finally, for side a:
[tex]\dfrac{\sin 104}{25}=\dfrac{\sin 37.6}{a}[/tex]
[tex]a\approx 15.7[/tex]
Hope this helps!
