Answer:
The correct answer is:
by <em>rule</em> ASA rule of congruence.
Step-by-step explanation:
First let us prove
by rule ASA (rule of congruence).
<u>Congruent side:</u>
(Given)
<u>Congruent angles:</u>
1. By definition of perpendicular,
Also,

Therefore,
or you can say,
2. Common angle between
is 
In a nutshell, in
,
(Angle)
(Side)
(Angle)
are congruent to the following angle, side and angle of
:
(Angle)
(Side)
(Angle)
Therefore, by ASA rule of congruence, we can say
.
<em>Since both triangles are congruent</em>, the sides
and
are also congruent.
Y^2+5y the greatest common factor is y so
y(y+5)
...
4x^2-49 this is a "difference of perfect squares" which always factors to:
(a^2-b^2)=(a-b)(a+b), in this case:
(2x-7)(2x+7)
...
5s^2-20 GCF is 5
5(s^2-4) now the parenthetic term is a difference of squares so
5(s-2)(s+2)
