How can B be B' ?B is also shaded.

B pura nahi shaded, sirf C kay sath intersection wala part hai.

 

[Dream.Eater]

AUB means the whole A and B should be shaded but here it is not so it must be compliment. :/

But its only shaded in c's intersection so AUB is correct

Q18d Q21c???
plzzzzzzzzzzzz helpppppp!!!!!!!!!!!!!

B pura nahi shaded, sirf C kay sath intersection wala part hai.

But it is shaded,if it was complement it wouldnt be shaded at all.

A tip to work it out in the reverse

A U B means A n B are fully shaded in one line
C is shaded in one line

Area we have to shade(or in this case area shaded) is the area in which the lines overlap i.e 2 lines are present.

Could someone tell me how to do this ASAP?????
Thanks in advance!!!!

x = 124 (angle at center is twice ...)

Reflex angle of BOE = 360 - 124 = 236
y = 118 (angle at center ...)

EDC = 90 degrees
z = ... (angle sum in a triangle)

BCD = 62 + z
AED + BCD = 180 (cyclic quadrilateral)

Q15. HOW TO FIND Y?
YAAR KOI ALLAH KA BANDA BATA DE. APKI DISTINCTION AYE GI INSHA ALLAH.

The sum of angles in the figure is
(6 - 2) *180

= 720

3 * (53 + 40) + 3y = 720
find y


NOTE: I HAVE MULTIPLIED IT BY 3 AS IT HAS A ROTATIONAL ORDER OF 3

Yup In Sha Allah. Do remember me your prayers

x = 124 (le at center is twice ...)

Reflex angle of BOE = 360 - 124 = 236
y = 118 (angle at center ...)

EDC = 90 degrees
z = ... (angle sum in a triangle)

BCD = 62 + z
AED + BCD = 180 (cyclic quadrilateral)

Jazakallah Khair bro!!
I really needed to know how to'do this cause I suck at circle theorems.....

 

[Dream.Eater]

Uhmmm.. x=124? Please shade the chord that matches it with 62

X= 124 is the ms answer

What is BCO? (hey exploded diper, i found your lost brother )

Question 21 part c:
You formed an equation in part i) so put this are 4 into that equation and you'll find that it takes 30 minutes, however here it takes only 9 minutes so 9:30= 3:10

I don't get that tip. :c

 

[Dream.Eater]

What I am saying it. That for angle in centre x2 the angle at circumference, both angle originate off the same chord right?

Which chord linsk that?

The diameter???????

I was talking about the distintion neechay sey.
