hello some questions for bearings I have to draw these manually.

a man walks 3.6 kilometres on bearing 235 degrees from A to B.

draw a diagram and find how far B is west of A and how far B is south of A?

How to find the angles in the triangle?

a ship sails on bearing 324 degrees from port p to port q a distance of 160 nautical miles.It then sails east until it reaches port r , due north of p.

What is the bearing of port p from port q?

what is the shortest distance from port r to port p?

a ship sails from x to y on a bearing of 125 degrees.if x to y is 234 nm how far is y south of x?

cartesian plane

draw a diagram of the cartesian plane to show point p (1,3) and point q (-3,-2)

I know how to find gradient, midpoint and length but

draw a line 5x-4y-4=0

and explain why this is parallel to pq.

in the diagram calculate the angle made by line pq and the positive x axis.

a graph shows

time 0, 0.5, 1.0, 1.5, 2.0, 2.5, 3.0

temp C 54, 48, 42, 35, 30, 27 , 22

draw a scatter diagram and show line of best fit.

find the vertical axis intercept

write down the equation of the line describing the linear relationship between the temperature of the liquid and time of cooling.

use the equation to predict the temperature of the water after 3.5 minutes.

thanks
