Quadrilateral OPQR is inscribed inside a circle as shown below. what is the measure of angle O? you must show all work and calculations to receive credit.

∠ O = 88°

Step-by-step explanation:

For the inscribed quadrilateral

The opposite angles are supplementary, that is

∠ O + ∠ Q = 180, substitute values

2x + 2x + 4 = 180

4x + 4 = 180 ( subtract 4 from both sides )

4x = 176 ( divide both sides by 4 )

x = 44

Thus

∠ O = 2x = 2(44) = 88°

4 and 5)16.97 or 12√2

6)15.59 or 9√3

7)y = 15.59 or 9√3     x =27

8)17.80
