IF U ANSWER FIRST U GET BRAINLIEST (BUT HAS TO BE CORRECT)3/x=x/12

Correct answer is + or - 6

3/x = x/12

cross multiply

x^2 = 36

x = root 36

x = plus or minus 6

6

to solve this. = 3/x = x/12

=}. 3/x = x/12

by doing cross multiple

we get x^2 = 36

so, x=. √36

x=. 6

hope it helps

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.
