The diagram shows the position of the ship(S) and the marine base(B) the scale of the diagram is 1cm represents 10km. a)work out the real distance between the ship and the base.
b) Measure the bearing of B from S

a) 35km

b) 070 degrees

C) Check the photo to see what I did

Step-by-step explanation:

To get full marks look at what I did for question (c)

You have to use a protractor on letter s and make sure the 0 on the protractor is facing the letter (N). Now check where 90 degrees is and draw a line straight by using the ruler then use the compass as u can see in the photo, where (x) point is on the end of the compass is your answer {make sure the compass is 2cm which means its 20km. Also make sure to align the compass on the line you drawn}

Thank you

the solution is 12x-6y
