use below :- exterior angle = [ (far arc) - (near arc) ] / 2

OpenStudy (beccaboo333):

Awe my hunnybear can help you ^_^ he's very good in math.

ganeshie8 (ganeshie8):

becca :) u need to look at the circle from external point Y

OpenStudy (anonymous):

84-35=49 49/2= 24-5?

ganeshie8 (ganeshie8):

not exactly...

ganeshie8 (ganeshie8):

\(\large \angle Y = \frac{VW - XZ}{2}\) \(\large 35 = \frac{84- XZ}{2}\) solve XZ

ganeshie8 (ganeshie8):

let me knw if smthng doesnt make sense...

OpenStudy (anonymous):

so isnt that 84-35/2?

ganeshie8 (ganeshie8):

nope, cuz 35 is itself the "external angle", its not the "near arc"

ganeshie8 (ganeshie8):

ur goal is to find "near arc XZ"

ganeshie8 (ganeshie8):

so u need to solve above equation

ganeshie8 (ganeshie8):

\(\large \angle Y = \frac{VW - XZ}{2}\) \(\large 35 = \frac{84- XZ}{2}\) multiply 2 both sides \(\large 70 = 84 - XZ\) subtract 84 both sides \(\large -14 = -XZ\) multiply -1 both sides \(\large 14 = XZ\) which is same as : \(\large XZ = 14\)

OpenStudy (anonymous):

35?

ganeshie8 (ganeshie8):

35 is the external angle GIVEN.

ganeshie8 (ganeshie8):

question is about finding XZ

ganeshie8 (ganeshie8):

look at diagram bit long.. u will see 35 at the external angle Y

OpenStudy (anonymous):

I figured it out, thanks for your heeelp c:

ganeshie8 (ganeshie8):

np... u wlc :)
