Can someone tell me how to draw this triangle?


"The course for a bike race follows a triangular shaped trail. The first leg is a straight 6 kilometer ride. After that, the biker must turn 283 degrees to the left and follow the trail to the next turn. He must then turn again to the left 269 degrees and follow the path back to the finish line, which is exactly where he started."

What does this triangle look like. Interior angles will help.

Yeah, i have the angles right for sure. i think we are supposed to subtract from 360 to get the interior angles. I am not sure, tho

77, 91, and 12 would be the angles...
just subtract the length he turned from 360 (which would be a full circle) to find one interior angle...
then all the angles equal 180 so subtract the two angles you know from 180 to find the last one

The angles 90, 180, and 270 will help to think about 3,6, and 9 oclock.

There is no such triangle.

After the first 6km, he turns 283 degrees to the left. That's to say he doubles back and keeps turning another 103 degrees. So the second section of track (second side of the triangle) is at 103 degrees to the first.

Then, after some unstated distance, he turns 269 degrees to the left. Again, he has doubled back but this time continued to turn another 89 degrees.

So the first two internal angles of the triangle are 103 and 89. But these sum to 192, making the third interior angle -18 degrees.

Hence the path, as described, is not triangular, no matter what the lengths are.

Do you have the angles right?

    It'll be a bit weedy for someone of your physical proportions, unless it's a derestricted 2-stroke, which will be mechanically fragile and difficult to master. Look for a 250 at least.
