What reason can be used to complete this proof? m∠1=m∠3 because ∠1≅∠3. m∠1+m∠2=m∠smq and m∠2+m∠3=m∠rmt m∠1+m∠2=m∠rmt because you can substitute m∠1 for m�3. m∠smq=m∠rmt by the transitive property of equality. so, ∠rmt≅∠smq.

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
