Short answer: 0.69Take 100. 31% = 31, 100-31=69Of course, when you increase the result by 31 percent you do not get the 100 back. But that was not the question.But, for completeness what do I multiply by to get the number, when adding 31 percent, gives me the original number, it is 0.7633 (1/1.31)

Your measure start at 16. So that is the basis (unless stated otherwise) upon which you reference the change.
That is:
16
20−16

Answer:
<ECF = 45 degrees
Step-by-step explanation:
If ABCD is a square, then the diagonal AC divides angle <C and angle <A in two equal parts. Angles A and C are also 90 degrees each due to the act that the figure is a square. Therefore their bisection would render 90/2 = 45 degrees.
Notice as well that angle <ECF is opposite by the vertex to one of these 45 degree angles, and then it must measure the same amount (45 degrees).
So, <ECF = 45 degrees
