Aship sailed 5120 km from port x'to port y on a bearing of 345° it then sailed 448 km on a beari of 075 to port z. calculate, correct to the nearest whole number, the: (a) distance from z to x: (b) bearing of z from x (c) time it took to sail from x to z through y at a constant speed of 120 km/h 7.

-3

step-by-step explanation:

a drawing really does here:

so i draw the horizontal line y=2 and the vertical line x=-2 at this intersection i put b (this is where my right angle is going to be).   so point b is at (-2,2).   point a is 5 units long and is also on y=2 so this point has to be (3,2) or (-7,2) -doesn't matter i will go with (3,2).

now we know c is at (-2,y) we don't know the y yet bet we know that c is on x=-2.

we have the area of the triangle is .5bh=12.5

we know the base length is 5 (ab)

we have the height is (2-y) if you look at your

plug in

.5(5)(2-y)=12.5

solve for y to get the y-coordinate for c

2.5(2-y)=12.5

divide both sides by 2.5 giving:

2-y=5

now subtract 2 on both sides

-y=3

y=-3

entering that problem on the tube might get you an answer

i dont know if you cant find a way its best to actually add all of them start from 105 tho
