Use the Law of Sines to solve the triangle delta ABC where A

Use the Law of Sines to solve the triangle delta ABC where A = 84 degree, C = 34 degree and a = 45

Solution

A = 84 ; C = 34 ; B = 180 -84 -34 = 62 deg

a = 45

Apply sine rule: a/sinA = b/sinB

b = (45/sin84)*sin62 = 39.95

a/sinA = c/sinC

c = a*sinC/sinA = 45*sin34/sin84 = 25.3

So, we have all sides and angles of the triangle
