Question

in the following drawing find side AC if BC is equal to 12 round your answer to two decimal places

Answer 1

@markkboyy I'll answer yours if you answer mine

Answer 2

@markkboyy My question is already posted

Answer 3

yup

Answer 4

so using sin we get

sin 45 = AC / 12

sqrt2 /2 = AC /12

12 sqrt2 = 2AC

AC = 12sqrt2 /2

AC = 6sqrt2 = 6*1,41 = 8,46

AC = 8,46 so the second choice is right not first how you marked it

hope this will help you
