15) Draw and label a diagram to represent: M is between J and K. MJ = 6.6ft
JK = 7.1ft.
Find the length of MK. 7.1 – 6.6
16) Y is between C and D. CD = 2x + 10 YC = 3x – 9, YD = x + 5. Justify whether YC  YD .
3x – 9 + x + 5 = 2x + 10 CY = 3(7)-9 = 12
4x – 4 = 2x + 10
2x = 14
YD = 7 + 5 = 12
Yes, since CY has the same length as YD, they are congruent.

17) Given: MC  CN
MC = 4x – 3 and CN = x + 9, find the length of MC.
MC = 4(4)-3 = 13
4x – 3 = x + 9
3x = 12
X=4
18) What is wrong with this picture? Given: MC  CN
MC = 3 - 4x and CN = x - 7
3 – 4x = x – 7
If x = 2, MC = 3 – 4(2) = 3 – 8 = -5
10 = 5x
The length of a side cannot be negative.

21) If point K is between T and R, explain (in words) how you can find TR if you know TK and KR.
If K is between T and R, then T, K and R are collinear, which means TK + KR = TR. So, we can just add
up the segments that we know to find the total length.
