Answer: 67.2°
Step-by-step explanation:
To find angle C, we have to use cosine rule. Therefore,
12² = 8² + 10² - 2 × 8 × 10 × cosC
C = 82.8°
The bearing of A from C will be
= 150° - 82.8°
= 67.2°.
(2,1), (4,2), (6,3) or (8,4) are the numbers we will use to find the first differences which will give us the unit rate
2/1 = 2
4/2= 2
6/3= 2
8/4= 2
therefore this graph is linear and its unit rate is 2.
They are decreasing 20 miles per hour for every 1 hour in hours 7-10
