During a relay race, runner a runs a certain distance due north and then hands off the baton to runner b, who runs for the same distance in a direction south of east. the two displacement vectors a and b can be added together to give a resultant vector r. which drawing correctly shows the resultant vector?

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
