Answer
Find out the value of x .
To proof
SAS congurence property
In this property two sides and one angle of the two triangles are equal.
in the Δ ADC and ΔBDC
(1) CD = CD (common side of both the triangle)
(2) ∠CDA = ∠ CDB = 90 °
( ∠CDA +∠ CDB = 180 ° (Linear pair)
as given in the diagram
∠CDA = 90°
∠ CDB = 180 ° - 90°
∠ CDB = 90°)
(3) AD = DB (as shown in the diagram)
Δ ADC ≅ ΔBDC
by using the SAS congurence property .
AC = BC
(Corresponding sides of the congurent triangle)
As given
the length of AC is 2x and the length of BC is 3x - 5 .
2x = 3x - 5
3x -2x =5
x = 5
The value of x is 5 .
Hence proved
Answer:
A - 1 = w
Step-by-step explanation:
Step 1: Write equation
A = 1 + w
Step 2: Subtract 1 on both sides
A - 1 = 1 + w - 1
A - 1 = w
Answer:
(-2,5)

Answer:
x=9
Step-by-step explanation:
reverse the operation!
108÷12=9
It should work for most questions like this and is simple.
4 quarts = 1 gallon
8 quarts = 2 gallons
12 quarts= 3 gallons
16 quarts = 4 gallons
20 quarts= 5 gallons
24 quarts = 6 gallons
28 quarts = 7 gallons
32 quarts = 8 gallons 8 gallons is the answer
