Answer is √7 ( not A, not B)

Step-by-step explanation:

BD/AB = sin 60°

BD/2 = √3/2

BD = √3

AD/AB = cos 60°

AD/2 = 1/2

AD = 1

CD = 3 -1 = 2

BC = √BD² + CD² = √(3 + 4) = √7

step-by-step explanation:

once you graph it hit 2nd (the blue button) and graph

that takes you to a table of coordinates

on the left is x coordinates and on the right is y coordinates and an empty box

(you may have to scroll up/down in order to get ( x, 0)
