3/4 =12/c it’s about solving proportions

c=16

Step-by-step explanation:

3/4 =12/c

means : c/12 = 4/3

             3c = 48

             c= 48/3 = 16

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.
