Two cars lost in a blinding snowstorm are traveling across a large field, each thinking they are on the road, as shown in the figure on the left. They collide. If the distance x is 104 meters and the red car is travelling at 15.1 mph, how fast to the nearest hundredth of a mph was the blue car travelling? angles are 45 & 60 I just need the formulas and procedure how to solve this.
