Skipper Dan is sailing his ship through a swift current. Before entering the current, his ship was moving with a velocity (speed and direction) of vi. The direction of ői is due west, and its speed is 20 km/h.
Now that the ship is in the current, however, it is moving with a velocity 02. The direction of v2 is 40°
south of west, and its speed is 25 km/h.
(Assume "due east" is 0°, "due north" is 90°, and so on.)
What is the speed of the current?
km/h
(Round your final answer to the nearest tenth.)
In what direction is the current flowing?
(Round your final answer to the nearest degree. Your answer should be between 0 and 360°.)

∠acb = 8°

step-by-step explanation:

∠xba lies on the circle and is half the measure of the intercepted arc ax

hence

measure of arc ax = 2 × 42° = 84°

∠acb is outside the circle and is

∠acb = (arcab - arcax ), hence

∠acb = 0.5 (100 - 84) = 0.5 × 16° = 8°

john got lost so he didn't know what to do and it was crazy because he didn't except it

step-by-step explanation:

it would be 0.18 because when the other choices are converted they equal those two numbers.   hope this !

the diagram shows you   triangle def with de=4, df=9 and de≠df≠ef.

the sum of the lengths of two triangles' sides are always greater than the length of the third side:

substitute sides lengths:

then 5< ef< 13 (option 3 is true).

def is a scalene triangle with all sides of different lengths (option 5 is true, option 2 is false).

answer: correct choices are 1, 3 and 5
