Answer:
Step-by-step explanation:
cost of playing x games at Adams = 7.50 + 0.45x
cost of playing x games at Jims = 1.25x
1.25x = 7.50 + 0.45x
1.25-0.45x = 7.50
0.80x = 7.50
x = 7.50/0.80 = 9.375 , but x must be an integer.
The cost is never the same. When x ≤ 9, Adams costs more. When x ≥ 10, Jims costs more.
An exterior angle is an angle supplementary to one of the interior angles.
In other words, an exterior angle is the angle between one of the sides, and the extension of an adjacent side.
In the given diagram, the angle D is measured from one of the sides, but not to the extension of an adjacent side.
Therefore angle D is not an exterior angle.
Option D is the correct one!
