## Algebra and Trigonometry 10th Edition

Using the area formula: $\frac{1}{2}$b*c*sinA = $\frac{1}{2}$a*b*sinC = $\frac{1}{2}$a*c*sinB B = $54^{o}$ 30' a = 62 c = 35 There are 60 minutes in a degree so 30 minutes is .5 of a degree. Therefore, A can be rewritten as: A = $54.5^{o}$ Area = $\frac{1}{2}$62*35*sin(54.5) = 882.2
