Answer
194.7
Work Step by Step
Using the area formula:
$\frac{1}{2}$b*c*sinA = $\frac{1}{2}$a*b*sinC = $\frac{1}{2}$a*c*sinB
A = $103^{o}$ 15'
b = 16
c = 28
There are 60 minutes in a degree so 15 minutes is .25 of a degree. Therefore, A can be rewritten as:
A = $103.25^{o}$
Area = $\frac{1}{2}$16*28*sin(10325) = 194.7
