Answer:
14) 21.136505024965 m
15) 43.076759215619 km
Step-by-step explanation:
14)
let h be the height of the lighthouse:
tan(41.3) = 18.7/h
Then
h = 18.7÷tan(41.5)
= 21.136505024965 m
………………………………………
15)
90-71.4 =18.6
Let s be the distance that the plane flew
towards the south:
tan(90 - 71.4) = s/128
Then
tan(18.6) = s/128
Then
s = tan(18.6)×128
= 43.076759215619 km

Answer:
any solution of y = 3x -4
Step-by-step explanation:
The two equations describe the same line. There are an infinite number of solutions. Any values of x and y that satisfy either equation will satisfy both equations.
__
The graph shows the lines in different colors and textures, so you can see they are the same line.
