Answer:
Step-by-step explanation:
You can figure out the angle DBC by the alternate interior theorem. Angle DBC=56 degrees. You already figured out BD.
Since we know BD, BC, and the angle DBC we can use the Law of cosine to find CD
The law of cosine is
CD^2=BC^2+BD^2-2(BC)(BD)cos DBC
Plug in what we know
CD^2=18^2+12.1^2-2(18)(12.1)cos 56
CD^2≈228.8387
Find the square root to isolate CD.
CD≈15.1
Answer:

Answer:
a= 1
b= -1
c= 3
Step-by-step explanation:
''a'' and "b" are the coefficients of x^2 and x respectively, where "c" is the constant number.
When solving a quadratic equation all the variables and constants should be on one side, in this case: x^2 -x +3=0.
Here the coefficient of x^2 is one, of x is -1 and constant is 3.
