How do you model 15-25 on a number line?

To model 15 - 25 on a number line, first you draw a line and make enough lines for it to go from o to 30 on one side and 0 to -20 on the other. Then you start at the 15 mark and subtract by 25 by going to the left of 15, 25 times. Then you would get to the answer -10.

the answer for this question is : 360°

step-by-step explanation:

we have been given a triangle   we need to tell which one of these is a triangle below to map onto itself.

360° rotation is the complete rotation which eventually leads to the same figure which is given.

the correct will be, that is 360° that will cause the triangle below to map onto itself.
