what is the length of ab a 12 b 6 c 3 d 9

OpenStudy (anonymous):

lines opposite to equal angles have equal lengths. so AB=BC. => 4x=2x+6. => x=3 therefore length of AB = 4x = 12

OpenStudy (anonymous):

is it 12x then

OpenStudy (anonymous):

we have found out x=3. the answer is 12 only as AB=4x=4*3=12
