Because if you did not you would not have a exact answer.
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°.
Answer:
<u>y = x - 1/5</u>
Step-by-step explanation:
x - y = 1/5
5x - 5y = 1
5y = 5x - 1
<u>y = x - 1/5</u>
