Solve Triangle ABC 27 c 75 a 35Solutionusing sine law si

Solve Triangle ABC. = 27 , c = 75, a = 35.

Solution

using sine law

sin alpha/a=sin gamma/c

sin 27/35=sin gamma/75

sin gamma= 75 sin 27/35=

gamma= 76.6 degree

beta=180-alpha-gamma= 76.4 degree

Sin alpha/a=sin gamma/c

sin 27/35= sin 76.4/c

c= 35 sin 76.4/sin 27= 74.9
