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:
the answer is 37.68
Step-by-step explanation:
C=2 x pi x r
C = 2 x 3.14 x 6 the radius is 6 because you divide the diameter by 2 to get the radius which is 6 in thsi case.
2x3.14x6=37.68
Answer: number of tickets sold to adult = 566
Step-by-step explanation:
Let x = number of tickets sold by DCHS to students.
Let y = number of tickets sold DCHS to adults.
Tickets to Dundee crowns mr.dchs are $3 for students and $5 for adults.
This means cost of total tickets sold to students and adults is $3x and $5y respectively.
If DCHS collected $3943 for the tickets, then we have
3x + 5y = 3943 - - - - - -1
The number of adult tickets sold was 195 more than the number of student tickets. This means
y = x +195.
Put y = x +195 in equation 1
3x + 5(x+195) = 3943
3x + 5x + 975= 3943
8x +975=3943
8x = 3943-975= 2968
x = 2968/8 = 371
y = 371 + 195= 566

4(t - 8) + 20 = 5
Distribute the 4.
4t - 32 + 20 = 5
Combine like terms.
4t - 12 = 5
Add 12 to both sides.
4t = 17
Divide both sides by 4.
t = 4.25
#24)
17 = -5(3 + w) + 7
Distribute the -5.
17 = -15 - 5w + 7
Combine like terms.
17 = -8 - 5w
Add 8 to both sides.
25 = -5w
Divide both sides by -5.
w = -5
#26)
9 = -(r - 5) + 11
Distribute the -.
9 = -r + 5 + 11
Combine like terms.
9 = -r + 16
Subtract 16 from both sides.
-7 = -r
r = 7
