Use the given information to solve the triangle.


1) C = 145 degrees, b = 4, c = 14.



2) A = 150 degrees, C = 20 degrees, a = 200.

  • trigonometry -

    sinB = b sinC/c
    having B you now have A = 180 - (B+C)

    a = c sinA/sinC



    the second is easier. You already know that B = 10 degrees. now just use b/sinB = c/sinC = a/sinA
