A village P is 10km from a lorry station, Q on a bearing 065°.another village R is 8km from Q on a bearing 155°.calculate;1.the distance of R from P to the nearest kilometer and 2.the bearing of R from P to the nearest degree.

Step-by-step explanation:

find the difference between the two angles first:

155-65=90 degrees

d is the distance d:

d^2=a^2+b^2-2ab cos(90)

d^2=10^2+8^2-2(10)(8)cos(90)

d^2=164

d=√164=12.81

the bearing of R from P to the nearest degree:

180-155=35 degrees

step-by-step explanation:

once you graph it hit 2nd (the blue button) and graph

that takes you to a table of coordinates

on the left is x coordinates and on the right is y coordinates and an empty box

(you may have to scroll up/down in order to get ( x, 0)
