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.
To work out how much Luz earns, you simply have to follow 400/40=10, so
she earns $10/hour. We can therefore establish that if she works for 6
hours, she'll earn $60.
Answer:
d = 16, b = 73
Step-by-step explanation:
To find b, i knew that the angles were congruent, so they were both the exact same.
To find d, I knew that the 65 degrees and the missing value of d had to add up to 81 degrees, because those are congruent too. So, I just subtracted 65 from 81 and then I got the answer.
I hope I helped.
