    The side across from the 63° angle is 299.5 ft and the side across from the 56° angle is 278.7 ft.

    We will use the Law of Sines to solve this. First, the angle across from the 63° angle:

    sin 61/294 = sin 63/x

    Cross multiply:

    x*sin 61 = 294 sin 63

    Divide by sin 61:

    (x sin 61) / (sin 61) = (294 sin 63) / (sin 61)

    x = 299.5

    For the side across from the 56° angle:

    sin 61/294 = sin 56/x

    Cross multiply:

    x*sin 61 = 294 sin 56

    Divide both sides by sin 61:

    (x sin 61) / (sin 61) = (294 sin 56) / (sin 61)

    x = 278.7
