    The legs of a triangle with a hypotenuse that measures 15 units long have lengths that are equal to 15 times the sine or cosine of the given angle.

    leg 1 = (15 units) x (cos 19) = 14.18 units

    leg 2 = (15 units) x (sin 19) = 4.88 units

    The lengths of the legs are 14.18 units and 4.88 units.
