Find all solutions for a triangle with C = 130°, c = 17, and b = 5. Round to the nearest tenth.

a. A = 37.0°, B = 15.0°, a = 15.2

c. A = 37.0°, B = 13.0°, a = 13.4

b. A = 35.0°, B = 13.0°; a = 15.4

    C

    Step-by-step explanation:

    Use sine rule

    17/sin130=5/sinB

    (5*sin130) : 17=sinB

    sinB=0.2253017892

    B=sin^-1ans above

    =13.4

    A = (130+13) subtracted from 180=37°

    a/sin37=17/sin130

    =13.4
