1.Find the Lowest Common Denominator(LCD) of the fractions.
Rename the fractions to have the LCD.
Subtract the numerators of the fractions.
The difference will be the numerator and the LCD will be the denominator of the answer.

The answer is e because I look it up
Answer:
x = 6.6
Step-by-step explanation:
law of cosines:
x² = b² + c² - 2ac · cosX
x² = 5² + 8² - 2(5 · 8) · cos 55°
x² = 25 + 64 - 80· cos 55°
x² = 25 + 64 - 45.89
x² = 89 - 45.89
x² = 43.11
x = √43.11
x ≈ 6.6
