A pizza restaurant sold 23 cheese pizzas and 19 pizzas with one or more toppings. Fourteen of the cheese pizzas were eaten at work, and 11 of the pizzas with one or more toppings were eaten at work. Choose a pizza at random. Find the probability that:

a. It was a cheese pizza eaten at work.

b. It was a pizza with one or more toppings, and it was not eaten at work.

c. It was a cheese pizza, or it was a pizza eaten at work.

-12 > a

step-by-step explanation:

-11 > 1 + a

subtract 1 from each side

-11 -1> 1 -1+ a

-12 > a

80° is the measure of gh

step-by-step explanation:

circle f is congruent to circle j

we have two circle with center f and j.

both circles are congruent. the radius of the circle would be equal.

see the attachment for the circle.

we are given ∠efd ≅ ∠gjh

therefore, arc (ed) = arc (gh)     (∴ circle f is congruent to circle j)

but ∠dfe=80°=arc (ed)

therefore, arc (gh) = 80°

thus, 80° is the measure of gh

any of them that add up to 180 degrees.
