Answer:
a) CA + ED = 74
Step-by-step explanation:
The complete question is attached in the image
Solution
Here the two circles R and D are congruent and thus their radius will be equal
Hence, RA (radius of circle R ) = DE (radius of circle D)
Hence, CA + ED = CA + 42
Also, RC = CD
CA = CE + RA = 32
So, CA + EO = 32 +42 = 74
Answer: 4x-1
Step-by-step explanation:

The <em>correct answers</em> are:
B) ∠R is congruent to ∠C; C) ∠B is congruent to ∠Q; E) BC is congruent to QR.
Explanation:
Using the congruence statement, we can state that corresponding elements of the triangles are congruent. In the statement, ∠R matches ∠C; ∠B matches ∠Q, and side BC matches side QR.
Answer: B
Step-by-step explanation: When the number of observations is odd the formula is:
$ x_m = x_\frac{n+1}{2}$
When the number of observations is even the formula is:
$ x_m = \frac{x_\frac{n}{2}+x_\frac{n+2}{2}}{2}$
