Question

SOMEONE PLEASE HELP ME ASAP PLEASE!!!​

Answer 1

Answer:

140 degrees

Step-by-step explanation:

The sum of the angles on a line is 180. Since we know one of the angles is 40, you do 180-40 to figure out the other angle (DCB). The answer is 140.

Answer 2

Answer:

$x = 140 \: \: degrees$

Step-by-step explanation:

Angels in a straight line = 180°

Let the DCB angle be x

Given that,

ACD angle = 40°

Let's solve now,

$40 + x = 180 \\ x = 180 - 40 \\ x =1 40 \: \: \: degrees$
