OpenStudy (y1066380):

What's the steps?

OpenStudy (y1066380):

I would like to know.

OpenStudy (anonymous):

the steps are first take your finger and go to the nearest pair step two label step three solve

OpenStudy (y1066380):

Um.. the correct answer is E...

OpenStudy (anonymous):

oops I was wrong I mean to the nearest number and do circumference and multiply the diameter and solve so its E

OpenStudy (dumbcow):

lol circumference and diameter ???

OpenStudy (anonymous):

yes

OpenStudy (imstuck):

Can't wait to see this one...I can't figure it out to save my life!

OpenStudy (y1066380):

Oh I know it now

OpenStudy (anonymous):

ok

OpenStudy (y1066380):

converse of angle DOB = 114 * 2 = 228 i.e. angle DOB = 360-228 = 132 angle CBE = 180-114-20 = 46 (angle sum of triangle) so, x = 360-114-46-132 = 68 (angle sum of polygon)

OpenStudy (y1066380):

am I right?

OpenStudy (dumbcow):

@y1066380 first find angle B |dw:1406479382449:dw| then use that to find arc BC Arc AC = 2*B --> ArcBC = 180 - Arc AC then from secant-secant theorem angle 20 is half the difference of opposite arcs \[20 = \frac{1}{2}(BC - AD)\] solve for arc AD using arc BC Finally you can solve for "x" using fact that a quadrilateral has 360 degrees |dw:1406479763978:dw|

OpenStudy (anonymous):

yes you are correct @y1066380

OpenStudy (y1066380):

thanks
