A ship is stationary at sea. A tugboat is 27 km away at a bearing of
050°, and a yacht is 21 km from the
tugboat at a bearing of 320°.
Draw a scale diagram showing the
positions of the three vessels.
Use a scale of 1 cm: 3 km.
Use your diagram to find the distance of
the yacht from the ship to the nearest km.

step-by-step explanation:

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional
