## SFAdrienne 3 years ago Can someone check my answer please?

I think it's right, I just want to make sure.

I have another one I'd like checked as well.

what is mBD?

if it is angle CAD, then the first is correct.

I got 122 degrees for measure BD...

both answers are correct. (if my assumptions of the description is correct)

Okay. You're sure?

yup.

Thanks. :)

You're welcome :)

hey this answer is wrong . it is 32 degrees . um 100 % sure

which?

the first is obtained by 180-58. the second was obtained by (180-66)/2

It was 122, not 32.

16. pratyush5

i am talking about the first one

how did you get 32?

18. pratyush5

|dw:1359396541365:dw| now use angle sum property of triangle in either APD or PBC . yu' ll get 32

i think CBD=58?

if not then it's 32.

21. pratyush5

buddy , CBD cant be 58 bcoz the angle which arc AC subtends is angle CBA which is equal to 58 . so we get 32

ah. so that's what the notation mAC means

23. pratyush5

yup. i was also confused when i first thought of angle APC to be 58 but then its already given as 90 degrees .

My lesson said the correct answer was 122.
