<span>Product means, the answer of numbers being multiplied with
each other.
In the given situation, we need to find three numbers that will be multiplied
with each other to get a product which is 9000.</span>
<span>Now, let’s find the possible numbers to be multiplied:
=> 300 X 30 X 1
=> 9000 x 1
=> 9000
Or this one also applies:
=> 4500 x 2 x 1
=> 9000 x 1
=> 9000</span>
There are a lot of ways to get a product of 9000 by multiplying
3 digits.
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
A+B+C+D+E=540°
4X+5+7X+6X+10+5X-5+4X+10=540
26X = 520
X = 520 : 26 = 20°
E = 4X + 10 = 80 + 10 = 90 °
