What is the answer to this problem?

-2/3a = -4/6.

So, like the denominator is equal in all fractions, we only solve -4+5-1=0

The answer is 0/6= 0

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.
