The combined distance between CD and DE is CE, so...
2x+4 + 6 = x+14 Simplify like terms..
2x + 10 = x + 14 Subtract x from both sides..
x + 10 = 14 Subtract 10 from both sides...
<h2><u><em>
x = 4</em></u></h2>
Proof: 2 (4) + 4 + 6 = 4 + 14
8 + 10 = 18

Answer:
< FAD and <DAH make 90 degrees so they are complementary
<EAC and CAH make a straight line so they are supplementary
Step-by-step explanation:
Complementary angles add to 90 degrees
< FAD and <DAH make 90 degrees so they are complementary
Supplementary angles add to 180 degrees ( a straight line)
<EAC and CAH make a straight line so they are supplementary
