A is false but R is true (the mean of the last 3 values is not 8 since x=7)
The average of 45 and 19 is
32.

Answers:</h3>
- ST = 23
- RU = 8
- SV = 5
- SU = 10
====================================================
Explanation:
Focus on triangles SVT and UVT.
They are congruent triangles due to the fact that SV = VU and VT = VT. From there we can use the LL (leg leg) theorem for right triangles to prove them congruent.
Since the triangles are the same, just mirrored, this means ST = UT = 23.
-----------------------
Following similar reasoning as the previous section, we can prove triangle RVU = triangle RVS.
Therefore, RS = RU = 8
-----------------------
SV = VU = 5 because RT bisects SU.
Bisect means to cut in half. The two smaller pieces are equal.
-----------------------
SU = SV + VU = 5+5 = 10
Refer to the segment addition postulate.
The equation of a circle is (x - h)² + (y - k)² = radius² where (h, k) is the center.
If the diameter is 16, then the radius is 8.
Your equation is:
(x - 7)² + (y + 5)² = 64
