A total of 21 mice are chosen for a research experiment. Of them, 15 are female and the rest are male. They are held inside a 20-gallon tank. If the researcher doesn't know the gender of any of the mice and picks one up at random from inside the tank, what is the probability that the researcher chooses a male mouse? Convert the fraction to a decimal. Round to three decimal places.

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
