Answer:
7 1/12
Step-by-step explanation:
i took the test 1.13 Quiz: Distance on a Number Line
It's 0 because 10+10 = 20 then subtract 20 and you get zero.
Option A:

Solution:
ABCD and EGFH are two trapezoids.
To determine the correct way to tell the two trapezoids are similar.
Option A: 
AB = GF (side)
BC = FH (side)
CD = HE (side)
DA = EG (side)
So,
is the correct way to complete the statement.
Option B: 
In the given image length of AB ≠ EG.
So,
is the not the correct way to complete the statement.
Option C:
In the given image length of AB ≠ FH.
So,
is the not the correct way to complete the statement.
Option D:
In the given image length of AB ≠ HE.
So,
is the not the correct way to complete the statement.
Hence,
is the correct way to complete the statement.
Answer:
a = 12m
Step-by-step explanation:
In order to solve this problem we will need to know the Pythagoras theorem that states that in a right angled triangle the square of the hypotenuse (the side opposite to the right angel) is equal to the sum of the squares of the other two sides. This theorem can be written as an equation....

Now we can see that we can easily find the missing value by using this theorem. We just have to substitute the values. And we get the following
