Consider u= {x|x is a real number}
a= {x|x € u and x+2> 10}
b={x|x € u and 2x> 10}
which statement is true?

a: 5€a; 5€b
b: 6€a; 6€b
c: 8€a; 8€b
d: 9€a; 9€b

it would rotate about 180 degrees.

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
