I'm having trouble?

Question

Without the wind, a plane would fly due east at a rate of 150 mph. The wind is blowing southeast at a rate of 50 mph. The wind is blowing at a 45° angle from due east. What is the actual speed of the plane with the wind?

Answer 1

The east aiding component of the southeast wind will we of 50mph * sin 45°.   That equals 35.35 mph, so the total speed will be 150mph+35.35. That's 185.35 mph.

I'm not able to post a graph, sorry.

Cheers
