Wierd trig question
Hi, I'll be glad if anyone could help me with this one:
(A special trigonometry question)
A bus and a cab leave from point a
The cab towards point c, the bus towards b.
they both get there at the same time.
I should mention the points a,b,c create a simple noneven triangle.
After that, they both turn and drive across the line BC and meet at point D.
The cab driver the continues to point B, and then back to A
The bus driver "Cuts" the triangle and goes stright back to A from point D.
The cab driver arrives at point A 43.75 minutes after the bus.
The bus's speed is 56.25% of the cab's.
you need to use trig in order to find the Angle BAC
Be very greatful if anyone helps me out! :)
