(36 km)sin(30°) = 18 km
From that point, moving 7 km west makes his easterly position ...
18 km -7 km = 11 km . . . . east of O
_____
The sine of an angle is the ratio of the side opposite to the hypotenuse. You can find the length of the side opposite (the easterly motion) by multiplying the sine of the bearing angle by the distance of travel. A diagram can help.
