Step-by-step explanation:
The law of cosine states that:
, where C is the side opposite of angle theta, and A and B are the adjacent sides of the angle.
In this case, A is equal to 21, and B is equal to 30 (or it could also be the other way around). That means that:
(to nearest 6 digits)
The answer is 216 miles. 1.5 hours is 90 minutes. Multiply 2.4 times 90.
Sorry I don’t know this I would help but I don’t know
I’m not so sure, but I think it might be:
f(x)=x-1
Sorry if wrong
