Question

Anyone by chance know how to answer this geometry question I need help so bad

Answer 1

Answer:

x = -8 and BDC is 68 degrees.

Step-by-step explanation:

Combine -7x+12 and -8x+48 to get -15x+60.  Since BDA is a straight angle put the above equation to get -15x+60=180.  Subtract 60 from both sides to get -15x=120.  Divide -15 both sides to get -8 as your x value.  Plug in -8 to BDC, since both negatives are being multiplied, it would turn to a positive number which is 56, add 12 to get 68 as your final result for BDC.
