I'm assuming you only need the first triangle. You didn't specify. If you need it after I answer the first one I'll be happy to help though.
To find the area of a triangle you go b(h)/2=a
6cm(3cm)/2
18/2
Area=9
To find the perimeter you add all of the sides together.
4+4+6=P
4+10=P
14= Perimeter

Step-by-step explanation:
We are given
v = 18 m/hr west
θ1 = 285°
θ2 = 340°
After 1 hours, the distance traveled by the ship is
dv = 18 mi
The distance between the ship and the lighthouse is
d = 18 / cos 340
Solve for d<span />
