Answer: 5 and 7

Step-by-step explanation: The first sentence "one number is 5 less than another" tells us how we are going to set up our variables.

If we represent one of our two numbers as (X) the other number will then be (X - 5). Let's call (X) the larger number and (X - 5) the smaller number.

Now we can use our second sentence "Their sum is 19" to set up our equation.

X + (X - 5) = 19

2x - 5 = 19

    +5    +5

2x = 24

÷2   ÷2

 X = 12

Now if (X) the larger number is equal to 12 then (X - 5) the smaller number is (12 - 5) or 7.

Therefore, our two numbers are 5 and 7.

In order to know what the polygon is, you have to plot the coordinates. After plotting, it is obviously shown a form of a rectangle. After connecting the midpoints of the sides, it formed a (D) rhombus, not a kite.

Answer:

<76

Step-by-step explanation:

Remark

You can't do this problem unless CD and E are all on the same line. If they are, then you can use || line properties.

Properties

<ABG = x                       Given

<ABG = <BGF               Alternate interior angles are equal.

<BGF = x                       Substitute

x + 2x - 9 = 180             Consecutive angles in a ||gram equal 180 degrees.

3x - 9 = 180                    Add 9 to both sides

3x - 9 +9 = 180 +9

3x = 189                         Divide by 3

x = 63

<DHG = 2x - 50            Given

<DHG = 2*63 - 50         Substitute for x

<DHG = 76

<IDC  = 76

<DHG and <IDC are corresponding angles and are equal; it is a property of parallel lines.
