    In ΔABC, m∠A = 44° , m∠B = 48°, and a = 25.

    b: 26.74

    c: 35.97

    C: 88.00°

    Find c to the nearest tenth

    A + B + C = 180°

    C = 180° - A - B

    C = 180° - 44° - 48°

    C = 88°

    c/sin(C) = a/sin(A)

    c = a*sin(C)/sin(A)

    c = 25*sin(88°)/sin(44°)

    c =~ 35.966990016932556967802733722836

    C = 180-A-B = 88°

    Law of Sines

    c = (a·sinC)/(sinA) ≅ 36.0 units
