# 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°:

2x+ 2x + 4° = 180°4x = 176°x = 176°/4x = 44°The angle O measures:

2*44° = 88°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°

i think it's b

step-by-step explanation:

because the graph is 2 above (0,0)

amount of oatypop that contains the prize = 40%

amount of oatypop which doesn't contain the prize = (100-40)=60%

probability that hannah will win a prize

= s +f s +f f s+ff f s+ff f f s+ infinity.where f= failure,s= success

= or 60%

probability that hannah only has to buy 3 or less boxes before getting a prize= (s) and ( f s) and (ff s) and (f f f s)

= = 87.04 %
