What is the domain of f(x) = cos(x)? the set of real numbers Negative 2 pi less-than-or-equal-to x less-than-or-equal-to 2 pi the set of real numbers Negative 1 less-than-or-equal-to x less-than-or-equal-to 1 the set of real numbers 0 less-than-or-equal-to x less-than-or-equal-to 2 pi the set of all real numbers

the least value out of the data shown is 5, maybe if you post a picture with it i could a little more.

step-by-step explanation:

2nd one in the first row is correct

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

sorry i got nothing
