"An angle that forms a linear pair with one of the interior angle the triangle" is the best definition of an exterior angle of a triangle.
<u>Option: C</u>
<u>Explanation:</u>
When to the sum of the inward angles opposite outer angle of a triangle the sum of the inward angles opposite is equivalent thus understood as exterior angle of a triangle.
The Triangle outer angle theorem for more about is if at each vertex the equivalent angle is drawn, the outer angles always add up to 360°. In reality, this is valid for any convex polygon, not just triangles.
In the most easiest pattern , since any angle of triangle equivalent is 60′, the outer angle would be 120′. Therefore all exterior angles sum is:
120 + 120 + 120 = 360°.

Answer:
nick's number = 91
eddie's number = 39
Step-by-step explanation:
n = nick's number
n = eddie's number
n -
n = 52
n = 52
cross-multiply: 4n = 52(7)
4n = 364
n = 364/4 = 91
eddie's number:
· 91 = 273/7 = 39
10x-5x=1000
x=200
she must sell 200 necklaces
hope this helps
