If ∠Q measures 18°, r equals 9.5, and p equals 6.0, then which length can be found using the Law of Cosines?

r
p
PR
PQ

Option C:

Length of PR can be found.

Solution:

Given data:

Length of r = 9.5

Length of p = 6.0

Measure of ∠Q = 18°

To find which length could be find in the triangle:

Using Law of cosines:

Substitute a = q, b = r, c = p and A = Q

Length of PR = q

Hence we can find the value of PR using law of cosines.

Option C is the correct answer.

the functions have the same rate of change i think. i narrowed it down to this answer and "the rate of change of tour 1 is greater" but i got it wrong using that answer so im assuming its the answer above. (this is a question i also answered from the iready site if anyone needs a reference)
