V + F = E + 2
Plugging in the given values:-
6a + 4a = 8a + 2 + 2
10a - 8a = 4
2a = 4
a = 2

In the given question, the two sides of the given triangles are parallel, so the the two corresponding angles of the Triangles are equal to one another.
Therefore, the Triangles are similar by AA similarity criteria ~
And since they are similar, the ratio of sides of one Triangle will be equal to ratio of corresponding sides of the other Triangle.
that is ~
Hence, value of l = 15.4 units ~
Sin(72) = s/t = s/21
so
s = 21 * sin(72)
s = 21 * 0.95
s = 20 cm
You're correct
Answer:

Step-by-step explanation:
We have the two functions:
and
.
We want to find
.
So, let's use the second function to find
first:

Divide:

Add:

Therefore, our expression is the same to
.
Now, we can substitute 5 for f(x). This yields:

Multiply:

Subtract:

So:

And we're done!
Answer:
Thus Volume of pool is 
<u><em /></u>
<u><em>GIVEN:</em></u> A swimming pool 20.6 m long 8.5 m wide and height 1.7 m
<u><em>TO FIND:</em></u> Volume of water needed to fill it.
<u><em>SOLUTION:</em></u>
<em>Length</em> = 20.6 m
Width = 8.5 m
<em>Height = </em>1.7 m
<em>Volume = L × B × H</em>
<em>→ </em>
<em />
<em>→ </em>
<em />
