Answer:
17. 10
Step-by-step explanation:
1. A segment going from an endpoint to the midpoint of the original segment is going to be 1/2 of the original segment. 
        AM = 1/2 AB
2. You know that the length of AM is 5, so plug that in a solve algebraically
        5 = 1/2 AB
        (2)5 = (2) 1/2 AB
        10 = AB
Answer:
18. 30
Step-by-step explanation:
The sum of two segments spanning from the original segment's midpoint to the end equals the length of the original segment. Because the midpoint is exactly in the middle of the original segment, the two other segments should equal each other. 
1. You need to first find the length of the two segments by setting them equal to each other and plugging in their equations.
        5x = x+12
2. Solve algebraically        
        5x = x+12
        4x = 12
        x = 3
3. Plug z into the equations for each segment and add them together.
        RM = 5(3)                                                   MS = (3)+12
        RM = 15                                                      MS = 15
                                            15+15 = 30

Complete Question:
The deck that Amos is building is in the shape of a parallelogram, DGRY.  The measure of D is five-halves the measure of Y. Find the measure of  each angle of the deck.
Answer:


Step-by-step explanation:
Given
Shape: Parallelogram DGRY
Dimension: 
Required
Find the measure of each angle
D and R are opposite sides & G and Y are also opposite sides.
So, we have:

and

The sum of angles is given as:

Substitute values for 

Take LCM


Multiply both sides by 





So:






Hence:

Answer: 4/5
Step-by-step explanation:
0.8 is 8 tenths which is 8/10 in fraction form
8/10 with both sides divided by two is 4/5
