Find the area of the triangle having the indicated angle and

Find the area of the triangle having the indicated angle and sides. C=84 30\', a=16, b=20

angle C = 84⁰30\'

1⁰ = 60min( 60\')

1\' = ( 1/60)⁰

angle C = 84⁰30\' = 84⁰ + ( 30* 1/60) ⁰

= 84.5⁰

area = (1/2)*a*b*sin C

= (1/2)*16*20*sin( 84.5)

= 159.26 sq units
