Answer:
12
Step-by-step explanation:
As there are 7 values in the given set, and one is missing, then the full set comprises 8 values.
2,7,8,14,15,20,29.
The middle value is 14 so we need another value, v such that, ½(14 + v) = 13.
This solves as v = 12.
The full set now is,2,7,8,12,14,15,20,29.
The answer for the first question is the second option.
The answer for the second question is 192
Answer:

Step-by-step explanation:
step 1
Find the measure of arc PK
we know that
The measure of the inner angle is the semi-sum of the arcs comprising it and its opposite.
Let
x------> the measure of arc IV
y ------> the measure of arc PK

substitute the values and solve for y



The measure of arc PK is 
step 2
Find the measure of angle VPL
we know that
The inscribed angle measures half that of the arc comprising
Let
z------> the measure of arc VK
y ------> the measure of arc PK

substitute the values

Answer:
c. (3, 2)
Step-by-step explanation:
Equating the values of y :
- -x + 5 = x - 1
- x + x = 5 + 1
- 2x = 6
- <u>x = 3</u> [x-coordinate of the solution]
Finding y by substituting x in one of the equations :
- y = x - 1
- y = 3 - 1
- <u>y = 2</u> [y-coordinate of the solution]
Solving :
- Solution = (x, y)
- Solution = (3, 2)
