Step-by-step explanation:
AS=∅πr²/360
where ∅=52°, R=10
AS=52°×π×(10)²/360
AS=14.4π
32 / (14 2/9) =
32 / (128/9) =
32 * 9 / 128 =
288 / 128 =
$ 2.25 per km

Answer:
x = 68°
Step-by-step explanation:
∠ DCB = ∠ EDC = 27° ( alternate angles )
Thus ∠ ECB = 23° + 27° = 50°
The sum of the 3 angles in a triangle = 180°, thus
x = 180° - (62 + 50)° = 180° - 112° = 68°
