To condition in which we can justify if the forces are pulling at right angles to each other is that the sum of the squares of the two lesser number should be equal to the square of the third number. 

For the first set: 12 lb, 13lb, 19lb. 

                                             12^2 + 13^2 <span>≠ 19^2

For the second set: 15 lb, 36 lb, 39 lb

                                             15^2 + 36^2 = 39^2

The first pair of forces do not pull at a right angle while the second do.
Thus, the answer is letter B. </span>

What is the slope of a line that is parallel to the line y = x + 2?
BigorU [14]
A slope of any line parallel to y = x + 2 will be 1. 

The slope of parallel lines are always equal. Since we do not see a number next to the x in the original equation, there is an assumed 1 there. Therefore any line that is parallel with it would also have to be 1.
