4. Because when they are a linear pair and together they form 180 degrees.

5. Angle 1 and 2, angles 2 and 3 are linear pairs. And linear pairs always form 180 degrees. So, they are both equal.

Mila [183]

Answer:

<em>The correct option is :  C.  3.4</em>

Step-by-step explanation:

The probability that a person shopping at a certain store will spend less than $20 is 0.2

A parabolic microphone used on the sidelines of a professional football game uses a reflective dish 24 inches wide and 6 inches
Strike441 [17]
The answer is a.
When you are solving problems like this you would use the equation y^2=4ax. The x and Y would be the coordinates. Based on the equation you have given the coordinates would be (6,12) and (6,-12), (24 is split up evenly between the y-axis).  
Then we go on to solve the equation by plugging in the numbers 12^2=4a(6)
144=24a
144/24=24a/24
6=a
