Suppose you are given information about a triangle according to SSS, SAS, and ASA. For which of these can you immediately use the Law of Cosines to find one of the remaining measuress

If you're only allowed one answer, then I'd say the best answer is SAS. If multiple answers are allowed, then SSS can be included.

Explanation:

With SSS, you can use the law of cosines to find any or all of the three angles. You'll have to do a bit of algebra to isolate the angle.

With SAS, you can use the law of cosines

Law of cosines

c^2 = a^2+b^2 - 2ab*cos(C)

we have 'a' and 'b' as the two sides, with C as the included angle (it is between sides 'a' and 'b')

Don't forget to apply the square root to both sides to fully isolate the missing side c.

You cannot use the law of cosines with ASA. There isn't enough information. However, you can use the law of sines to figure out the other side lengths. Keep in mind that you'll need to determine the third missing angle first.

1 mph

step-by-step explanation:

if the question is asking how much does she drive per mile then,

13 / 13 = 1 mph
