ganeshie8 (ganeshie8):
you need to find that angles. that angle is called 'inscribed angle'
ganeshie8 (ganeshie8):
use this :- inscribed angle will be half of central angle.
OpenStudy (anonymous):
How do i find central angle?

ganeshie8 (ganeshie8):
thats central angle
OpenStudy (anonymous):
Okay so half of 68?
OpenStudy (anonymous):
is 34 the inscribed angle
ganeshie8 (ganeshie8):
Yes ! thats right !

So the answer is 34?
OpenStudy (anonymous):
@ganeshie8 I need help for another problem
ganeshie8 (ganeshie8):
sure ask :)

its a cyclic quadrilateral
ganeshie8 (ganeshie8):
use this :- opposite angles are supplementary in cyclic quadrilateral
OpenStudy (anonymous):
So what is the angle I measure?
ganeshie8 (ganeshie8):
<VTS + 60 = 180
OpenStudy (anonymous):
So 120 counts?

120 + 60?
ganeshie8 (ganeshie8):
<VTS + 60 = 180
<VTS = 120
OpenStudy (anonymous):
Ok.
OpenStudy (anonymous):
@ganeshie8 In circle A find the mDB

same as furst q. use inscribed angle formula
ganeshie8 (ganeshie8):
mDB = C x 2
= 71 x 2
OpenStudy (anonymous):
180-71 = ?
OpenStudy (anonymous):
Using that formula?
