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.

Answer:
2n-7
Step-by-step explanation:
"7 less than twice a number n"
is the same as
"7 less than (twice a number n)".
I put ( ) around that one part because I want you to focus on that part first.
Twice a number n means 2 times that number n or 2n.
So now we have
"7 less than 2n".
This means 2n-7.
Answer:
∠Q ≈ 42.969, ∠P ≈ 52.03, QR ≈ 15.036
Step-by-step explanation:
Law of sines:
13/sin Q = 19/sin 85°
=> sin Q = 13 × sin 85°/19
=> Q = sin^-1 (13 × sin 85°/19)
=> Q ≈ 42.969
∠P=> 180 - 85 - 42.969 ≈ 52.03
QR/sin 52.03° = 19/sin 85°
=> QR = sin 52.03° × 19/sin 85°
=> QR ≈ 15.036
No, she cannot afford the car.
The total would be $176, and she only has $160.
Hope this helps!!
