The domain of this expression is all real numbers except where the expression is unidentified. In this case, there is no real number that makes this expression unidentified.
If 3 + 6(2 + 3/6) is actually the power, then simplify 3 + 6(2 + 3/6) as a first step. Must follow Order of Operations rules (PEMDAS): mult and div BEFORE addition and subtraction.
Thus, 3 + 6(2 + 3/6) = 3 + 6 (15/6)
= 3 + 15 = 18.
Then: 3^18 is the answer. You could expand this if you wanted, but what would be the point of that?
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°.
