    Im not sure if i'm correct, but i think the answer is BC = 40ft

    Step-by-step explanation:

    30º 60º 90º Triangle (i think)

    x = 20ft

    2x = 40ft

    x sqaureroot of 3 = 20 squareroot of 3

    I think that BC would be 10 degree angle because there are 180 degrees in a triangle and is A is 90 B is 60 and AB is 20 thats 170 leaving 10 left over
