160 is 120% of what number? show your work,

This is a simple question, where the calculation has to be done with clarity for understanding.
Let us assume the unknown number = x
Then we can write the equation as
120x/100 = 160
120x = 160 * 100
120x = 16000
x = 16000/120
   = 1600/12
   = 133.33
So the unknown number is 133.33. It is not a perfect result but on approximation it can be seen that it is the nearest answer that can be reached. I hope the procedure of doing such problems is clear to you.

Step-by-step explanation:

Two triangles are congruent by AAS postulate if two adjacent corresponding angles are congruent and the next adjacent sides to any of the angles is are also congruent. The adjacent sides should not be in between the two congruent angles.

From the triangles RQS and UTV

The adjacent side to is RQ and for is UT.

Similarly, the adjacent side to is QS and for is TV.

So, the possible sides that could be congruent by AAS postulate are:

or

So, the correct option is
