The way to do it can be explained like this:
Say AB and CD are the two parallel lines cut by a transversal at E and F respectively.
Then the pairs of alternate interior angles are:
Angle(AEF) and Angle(DFE)
Angle(CFE) and Angle(BEF)
Now lets prove if this is true:
<span>Angle(CFE) +Angle(DFE) = 180
(linear pair)
Also
Angle(CFE) +Angle(AEF) = 180
(Corresponding angles)
</span><span>Equate the above results:
Angle(CFE) +Angle(DFE) = Angle(CFE) +Angle(AEF)
</span><span>Angle(DFE) = Angle(AEF)
</span>Happens the same with
<span>Angle(CFE) = Angle(BEF)
</span>Hope this is very useful for you
Answer:
Integer = -40
Step-by-step explanation:
40 x -1
= -40
Therefore, -40 is the integer.
Answer:
Step-by-step explanation:
Answer:
x = 24/15 = 8/3 = 2 2/3
Step-by-step explanation:
remember what you do to the left you must do to the right.
I converted the -5 to -15/3 so I could easily add or subtract
-5/3 x = -8/3
multiply both sides by -3/5 to cancel the coefficient of the x
x = -8/3 * -3/5 = 24/15
