Determine the distance AB across a lake using the following data: AC = 400 m, angle C = 90°, and angle CAB = 40°. Round the answer to the nearest meter.
Solution:
I say AB = 400/[Cos 40] = 522 meters
I then know the distance AB across the lake = 522 meters.
I timed myself for this one. I did it in 5 minutes.
Is any of this right?
