In a certain university, 60% of the academic staffs are senior lecturers (A), 25% are associate professors (B) and 15% are professors (C). Due to stress, 45% of the senior lecturers suffer from high blood pressure, 40% of the associate professors suffer from high blood pressure, and 70% of the professors suffer from high blood pressure. If an academic staff is randomly selected, what is the probability that he or she is a professor given that he or she has a high blood pressure

i think it is 70

step-by-step explanation:

the answer is 48m^2!

step-by-step explanation:

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
