Proof:
and
are isosceles triangles.
Explanation: Given in
D and E are angle bisector of
and
respectively.
Where G and H are points in AB such that
and
.
Let us take two triangles
and 
(Right angles)
BE=BE, (common segment)
( Because BE is angle bisector)
Thus,
(ASA)
Therefore, EH= CE (CPCT)
So, in
, EH=CE ⇒
is an isosceles triangle.
Now, in
and
,
(Right angles)
AD=AD (common segment)
( Because AD is angle bisector)
⇒
(ASA)
Thus, CD=DG (CPCT)
So, in
, CD=DG ⇒
is an isosceles triangle.
15s=2550
(divide both sides by 15)
S=170

Answer:
32.6
Step-by-step explanation:
when you plug in for s and r you will get 66-33.4 since 5.5 multiped by 12 is 66 and 8.35 multiplied by 4 is 33.4 .
then you subtract them and that's how you'll get your answer
Figure B is the answer!
The formula for the Pythagorean theorem is
A^2+B^2=C^2
In figure B the units are squared. Making it your answer.
