Anumber a is fewer than -6 or no less than - 3

I am not sure what your asking but if it is what i think it is, then a number cant be less than -6 but not less than -3 because -3 is greater than -6. so its impossable (if it is what i think you mean)

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.
