OpenStudy (fibonaccichick666):

is QPR a right angle?

OpenStudy (fibonaccichick666):

oops didn't see the arc

OpenStudy (clamin):

they are inscribed angle

OpenStudy (fibonaccichick666):

ok so, what relation do you have about the subtended arc and the angle that makes it?

OpenStudy (fibonaccichick666):

hold on, over complicated it

OpenStudy (fibonaccichick666):

does QR pass throught the center?

OpenStudy (clamin):

i guess thats the arc of the angle

OpenStudy (fibonaccichick666):

no it isnt, hmm let me think on it for a min

OpenStudy (clamin):

kk

OpenStudy (anonymous):

is 160 arc length or circumference

OpenStudy (fibonaccichick666):

sorry I was gone so long, I was trying to not lose my mind. So the picture is the only given info correct?

OpenStudy (anonymous):

if you have 160 as the outside arc, using inscribed angle theorem you can safely say that angle P is 80.

OpenStudy (anonymous):

80 + 57 + 3x+13 = 180

OpenStudy (anonymous):

150 + 3x = 180 3x = 30 x=10

OpenStudy (clamin):

@ferrariwindows77 where did u get that 80?
