Answer:
The Answer for part be is 65.5584
Step-by-step explanation:
A=4,
b=3,
c= 2
a² + b² -2abcosC =c²
a² + b² - c² = 2abcosC
2abcosC = 4² + 3² -2² = 16 + 9-4= 21
Answer : B.21
Is this a question? if it is it’s x over the x times 45
Remember that a natural log undoes the e, so they cancel each other out and your result is -3.
