Answer:
Step-by-step explanation:
The equation of a circle is where
is the center of the circle and
is the radius of the circle.
Given that and it passes
, their distance between each other must the radius of the circle, so we can use the distance formula to find the radius:
Therefore, if the length of the radius is units, then
, making the final equation of the circle
Option C:
We can find the value of PR using law of cosines.
Solution:
Given data:
∠Q = 18°, r = 9.5, p = 6.0
To find which length could be find in the triangle:
Law of cosines:
Substitute a = q, b = r, c = p and A = Q
If we substitute the values given, we can find q.
q = PR
Hence we can find the value of PR using law of cosines.
Option C is the correct answer.
