ΔABC ≅ ΔEDC by the SAS postulate.
<h3>What is the SAS postulate's conclusion?</h3>
Postulate of Side-Angle-Side (SAS) ,The two triangles are said to be congruent if two sides and the included angle of one triangle match those of another triangle by two sides and the included angle.
According to the SAS Postulate, two triangles are congruent if their two sides and included angles are identical to those of another triangle's two sides and included angle
The midpoint of DB and AE Given is at C.
BC ≅ CD Two equal portions are produced by the midway C.
AC ≅ CE Two equal portions are produced by the midway C.
ACB and DCE Congruent vertical angles exist.
By the SAS postulat, ABC becomes EDC.

Answer:
21600
Step-by-step explanation:
24x10x90=
240x90=
21600
Step-by-step explanation:
Volume =pir^h
V1=pi r1^h
V2=pir2^2h
Now,V1/V2=r1^2/r2^2
v1/v2=r1^2/(1.05)^2 ((r2=r1+5/100r1)
v1/v2=1/1.1025
v1/v2=0.907
(v1/v2-1)=0.0907×100%
(v1-v2)/v2=9.07%
increase in volume is 9.07%
Let
T = theta
Use the Law of Cosines to get
c^2 = a^2+b^2 - 2ab*cos(T)
<span>7^2 = 10^2+8^2 - 2*10*8*cos(T)
</span><span>49 = 164 - 160*cos(T)
-160cos(T) = 49-164
</span><span>-160cos(T) = -115
</span>cos(T) = -115/(-160)
cos(T) = 23/32
cos(T) = 0.71875 which rounds to 0.72
The final answer is C) 0.72
