Step-by-step explanation:
Let speed of boat in still water is s.
Distance proportional to speed
90/10 = (s+ 4)/(s - 4)
=> 9s - 36 = s + 4
=> 8s = 40
=> s= 5 mph

1 yard = 3 feet
2 yards = 6 feet
2 feet * 3 = 6 feet
so 5.5 ft * 3 = 16.5 feet, so pole is 16 feet 6 inches
Place the point of the compass on point J and draw an arc in the interior of the triangle.
78, because you have to do the inverse operation so 80/2= 40 then 40-1= 39 and 39*3 = 78
