question no 26 (a)

<BCD=<BAC ===> <C=<A
<DBC=<CBA ===> <B=<B

and the ratio = BC :BD
6: 4 => i.e 3:2

Srry its the b part i wanted to ask

 

[Spidey21]

Srry its the b part i wanted to ask

ration it
AB= 4+x

so ration it like this
4+x/6 = 6/4

remember i kept the bigger triangle on the top..
x=5.

But arent corresponding sides kert equal ?
Can u also explain me a little about similar triangles

well the similiar triangles are not completely equal but have 2 things same
like they might have an angle same and a side same which will make it a similar triangle...

Thnx

Thnx

np...
btw i shared a link on your wall..check that its DAMN helpful..

1)similar triangles same angles of of a particular side of both triangle
suppose triangleABC= triangleXYZ therefore <A=<X ,, <B=<Y ,, <C=<Z

2) and they have same ratio of concerned sides
suppose triangleABC= triangleXYZ

then AB/XY= BC/YZ = AC/XZ

hoped understand!!

is fx 82ES allowed for olevels?
anyone please help..!

anyone please help..!

yup it is allowd..!!!

 

[hellangel1]

yup it is allowd..!!!

thank yew..

 

[falcon678]

thank yew..

 

[falcon678]

by the way guys is fx-911es allowd..???

by the way guys is fx-911es allowd..???

dont know .... Scratch out the model number with any sharp object !!

ITS A MARKING SCHEME URL

pls post correct paper url

yeah nd its changed..

question no. (1)(b)(i), (5)(c), (8)(d)(i)(b).

1b(i)
it will be 13 hours and 16 mins

5c
(i)4/25x3/24 =1/50 will be the answer..
(ii)2/25x5/25=1/30

i would have done 8 if i had graph.

question no. (1)(b)(i), (5)(c), (8)(d)(i)(b).

q(1)(b)(i) just difference from may 7 to may 6 i.e 00 36+24 ( add 24 bcuz of being next day)

24 36 - 11 20 => 13h 16m

5(c) for 1 time it would be 4/25 and for second 3/24 multiply both

(ii) little bit confused according to my knowledge we should do 2/25 x 5/24 and ans should be 1/60 but correct ans = 1/30!!!
