PLEASE HELP ! WILL GIVE 100 POINTS + BRAINLIEST ! 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.

Step-by-step explanation:

The quadrilateral OPQR is cyclic quadrilateral.

It has a property that opposite angles are supplementary.

The angles O and Q sum to 180°:

The angle O measures:

Angle O = 88°

Step-by-step explanation:

∠O + ∠Q = 180°

(2x) + (2x + 4) = 180

4x + 4 = 180

4x = 176

x = 44

∠R + ∠P = 180°

(3y + 8) + (y) = 180

4y + 8 = 180

4y = 172

y = 43

Angle O:

= 2x

= 2 (44)

= 88°
