I'm in grade 10 doing Sine Law at the moment and I need help with two questions.
#1 "A ship leaves port and sails 18 km north. It then veers off course 30 degrees east. One hour after this change of course, the ship's instruments indicate that the vessel is 36.7km from port, as the crow flies. How far has the ship travelled since it changed course?"
My teacher says it is 28km for the answer, I did it many times but I didn't get this answer, can someone show me the steps please?
Here is a picture I drew on the computer from my homework sheet for Question #1
#2 "The sides of a parallelogram measure 5 cm and 3cm. Calculate its area if diagonal AC is 7.65cm"
My teacher says it is 8.64 cm2, but I didn't get the answer
if you replied to my post, can you pm me please? I need help for a test soon. Thanks.
