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?
You're welcome :)
hey this answer is wrong . it is 32 degrees . um 100 % sure
the first is obtained by 180-58. the second was obtained by (180-66)/2
It was 122, not 32.
i am talking about the first one
how did you get 32?
|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.
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
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.
so...i guess the first interpretation was right.
