Answer:
78.5 km
Step-by-step explanation:
Measured at the airport, the angle between the two planes is ...
180° -60° -50° = 70°
The law of cosines tells us the distance between the planes is ...
d = √(50² +80² -2·50·80·cos(70°)) ≈ √6163.84 ≈ 78.5 . . . km
The planes are about 78.5 km apart.
300=x+1.9x
I got this by dividing the problem into two parts x[the speed of the first half] plus 1.9x [the speed of the second half increased by 1.9] both of those together should give you 300.
I went further and solved this...If you placed 103.5 into this problem for x you should get 300.15!
Answer:
Alternate Exterior Angles
Step-by-step explanation:
Alternate exterior angles are two angles on the opposite outer sides of two parallel lines cut by a transversal.
The two angles given, 2 and 7, are alternate exterior angles.
Hope it helps! :)
