Two buses leave a station at the same time and travel in opposite directions. one bus travels 12 mi/h faster than the other. if the buses are 690 mi apart after 5 hours, what is the rate of each bus mi/h?

step-by-step explanation:

2

step-by-step explanation:

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
