Question

In ΔABC, ∠A is a right angle and m∠B = 60. If AB = 20 ft, find BC.


​

Answer 1

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

Explanation:

30º 60º 90º Triangle (i think)

x= 20ft

2x = 40ft

x sqaureroot of 3 = 20 squareroot of 3

Answer 2

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
