Given f(x)=x^+7, find x if f(x) = 23

Step-by-step explanation:

23=x^2+7

16=x^2

Take the square root of both to get x alone

x=4

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.
