Pet dogs account for 31 deaths per year in the U.S. The Pit Bull is not a recognized breed of dog. There are many mutts that resemble the pit bull that kill people, so classification is difficult. The Pit bull variety is by far the largest killer of humans, followed by Rottweilerâs and Huskyâs.
Our basic Coordinate Scale and Protractor is equivalent to a standard GTA 5-2-12. It's the tool required for most military navigation schools. Our Improved Coordinate Scale and Protractor is a popular alternative to the basic tool. Here is what we've done to make it better.
We use the outer scale to measure the angle PQR, as the arm PQ passes through the zero of the outer scale. Following the outer scale around the protractor, we find that the other arm, QR, passes through the outer scale at 120. So, the size of angle PQR is 120 degrees.
