(i) In AABC, DE | AB,DC =2BDA(ACDE)=20 cm thenfind A(OABDE)​

Answer»

Answer:

The basic proportionality theorem STATES that if a LINE is drawn parallel to one side of a triangle and it intersects the other two sides at two distinct points then it DIVIDES the two sides in the same ratio.

It is given that AD=8 CM, AB=12 cm and AE=12 cm.

Using the basic proportionality theorem, we have

AB

AD

=

AC

AE

=

BC

DE

⇒

AB

AD

=

AE

⇒

8

=

AC

12

⇒8AC=12×12

⇒8AC=144

⇒AC=

8

144

=18

Now, CE=AC−AE=18−12=6 cm

Hence, CE=6 cm.

0.345 with bar in 345 write in p/q form answer with explanation I will give you the brainliest​

Answer»

Step-by-step EXPLANATION:

First CONSIDER x=0.345 345,because there is a bar above the 3 digits. The NUMBERS after the POINT repeats.Take this as 1.

Next multiply by 1000 on both the sides. Because ,as there is a bar on THREE digits we should write as 1000.Take this as 2.

Next we have to subtract 1 from 2.

that is 1000x =345.345 -

x = 0.345

-----------------------

999x = 345.000

------------------------

then we get 999x=345.000

999x = 345

x= 345/999

The GIVEN EXPRESSION has 7,11 and 17 as its factors.

∴ It is a composite number.
