Quadrilateral OPQR is inscribed in circle N, as shown below. Which of the following could be used to calculate the measure of ∠ROP?
(6x − 4)° + (2x + 16)° = 360°
(x + 16)° + (6x − 4)° = 360°
(6x − 4)° + (2x + 16)° = 180°
(x + 16)° + (6x − 4)° = 180°
THE ANSWER IS NOT C

the 4th   i think ?

Step-by-step explanation:

Since opposite angles are supplementary, if you add their measures, the sum equals 180.

That gives you an equation is only x, which you can then solve.

Once you know the value of x, you can plug it in the expression for angle O and find its measure.

Look in the 4 choices.

Which equation is the sum of the measures of the opposite angles you have expressions for and then set to equal 180?

these sign is used to tell weather the number is greater or less than the number   <   or >     but this sign means its equal =
