I am super confused about these-

I have two problems that I have no idea what to do with. I know I need to draw a picture but I do not understand the problems enough to draw the diagram. For each I will type out the problem as well as attach an image of the problems as I am doing them on the internet.

1. A ship headed due east is moving through the water at a constant speed of 8 miles per hour. However, the true course of the ship is 60°. If the currents are a constant 4 miles per hour, what is the ground speed of the ship? (Round your answer to the nearest whole number.)

2. A plane headed due east is traveling with an airspeed of 290 miles per hour. The wind currents are moving with constant speed in the direction 240°. If the ground speed of the plane is 145 miles per hour, what is its true course?

Help would be appreciated SO much!
