Please Help please !!! two planes leave Atlanta at 3pm est. one flies east and travels at a speed of 75 kilometers per hour slow

ASHA 777 [7]

Answer:645 kilometers per hour
Solution.
Let v be the speed of the plane flying east!
Then, the speed of the plane flying west is v+75.
Since the planes are 5460 kilometers apart by 7 pm est,
(7-3)*(v+(v+75))=5460
2v+75=1365,
2v=1290,
v=645
answer: 645

Which lines are parallel if ∠6 ≅ ∠4? Justify your answer.

bekas [8.4K]

<6 = <7 vertical angles

<1 = <4 vertical angles

if <6 = <4

then y is parallel to z because <1 = <7 alternate interior angles are equal
