Quadrilateral OPQR is inscribed in circle N, as shown below. What is the measure of ∠QRO?Quadrilateral OPQR is inscribed in circle N. Angle O is labeled x plus 17 degrees, angle Q is 6x minus 5 degrees, and angle R i4167113139
We know that the sum of all the inside angles of a quadrilateral is 360º, but we can't use that property because we don't know the angle Now that we know the value of x we just need to replace that value in the angle that we are searching for :
