A 360 degrees counter-clockwise rotation will bring the triangle at the same place.
So, divide 1980 by 360 and find the remainder.
On dividing, we can find that
1980 = 5(360) + 180
A 1800 degrees rotation will rotate the triangle 5 times and will bring it in the same place.
A further 180 degrees rotation will rotate the triangle to two quadrants back and will bring it in the first quadrant.
The lines are parallel. There is no solution.
Josh has hiked 17 km, which is 2 km away from being 1/2 done. You are welcome!
The slope is 3/2 or y = 3/2x - 1
