OpenStudy (raden):

AC/DC = BC/EC

OpenStudy (raden):

15/10 = (x+8)/8 solve for x

OpenStudy (anonymous):

Okay (:

OpenStudy (anonymous):

10x+80= 120

OpenStudy (anonymous):

10x=40

OpenStudy (anonymous):

x=4?

OpenStudy (raden):

yes, you are right. x = BE = 4

OpenStudy (anonymous):

Cool and what about the second question?
