A fishing boat has snagged a fish and want to know the depth of the fish. If the there is 18 meters of fishing line out and the angle of depression is 24º, how deep is the fish?
Round the nearest tenth of a meter.

7.3 meters

Step-by-step explanation:

hypotenuse = 18

angle depression = 24 degrees

missing side = opposite, x

since this has opposite and the hypotenuse were going to use sin

sin(24 degrees) = .40673664307

multiply .40673664307 by the length (18) = 7.32125957526 rounded down =7.3 meters

2(2x + 3) = -4 + 2(2x + 5)

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 6

4x - 6 + 6 = 4x - 6 + 6

4x = 4x

x = x
