FAN+MEDAL!! Quadrilateral OPQR is inscribed inside a circle as shown below. What is the measure of angle R? You must show all work and calculations to receive credit. Circle N is shown with an inscribed quadrilateral labeled OPQR. O is labeled 2x degrees. P is labeled y degrees. Q is labeled 2x plus 4 degrees. R is labeled 3y plus 8 degrees. Please help I don't umderstand..

opposite angles in an inscribed quadrilateral sum to 180 degrees, so... 2x + (2x + 4) = 180 (3y + 8) + y = 180 solve for x and y

oh okay thank you, anything else after that??
Vocaloid
  • Vocaloid
um, there's nothing more to tell you, all you need to do is solve the two equations
anonymous
  • anonymous
k workin on it now
Vocaloid
  • Vocaloid
well, actually, you can skip the first equation and just solve the second one
Vocaloid
  • Vocaloid
(3y + 8) + y = 180 find y

y=43 is that right?
Vocaloid
  • Vocaloid
yes, y = 43 now, the question wants the value of angle R, and angle R = 3y + 8, so R = ?

how do u do it?? im having a total brain fart right now... hmm
anonymous

omg i feel so stupid
Vocaloid
  • Vocaloid
y = 43 3y + 8 = 3(43) + 8 = ?
anonymous
  • anonymous
oh!! okay thx
anonymous
  • anonymous
it gives me 43 again..
Vocaloid
  • Vocaloid
3(43) = ?
