I am thinking of a number. If I double it, add five and then double, the result
the answer is 14. What number am I
thinking of?

well if you double 1 then that equals 2 then you add five is 7 then double it is 14...so...yeah whatever I just said

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.
