Answer:

Step-by-step explanation:

Here are some tips for how to split the bill when you are out with friends:

Splitting the Bill with Friends

To avoid any conflict, talk openly with your friends about sharing the bill as early as possible. Then, at the restaurant, ask the server if he or she can provide your party with separate checks. Even if the restaurant does not provide this option, asking this question will show everyone that you are only willing to pay for your portion. However, this approach only works if everyone hears your conversation with the server.

Find m∠DEC (the picture is not drawn to scale).

Answer:

M∠DEC equals 123º.

Step-by-step explanation:

The sum of a triangle's three angles always equal 180º. The exterior angle, x, equals the two non-adjacent interior angles.

180 - {(x - 45)+(x - 12)} = m∠DEC

m∠DEC + x = 180

(x - 45) + (x - 12) = x

Solving for x:

(x - 45) + (x - 12) = x

x - 45 + x - 12 = x Remove parenthesis

2x - 57 = x Combine like terms

2x = x + 57 Add 57 to both sides

x = 57 Subtract x from both sides

Finding m∠D:

x - 45 = ?

57 - 45 = 12º

Finding m∠C:

x - 12 = ?

57 - 12 = 45º

** (Checking x: 12 + 45 = 57) **

Finding m∠DEC:

AC is a straight line, and because straight lines are equivalent to 180º, we subtract 57 from 180:

180 - 57 = 123º
