If they have the same measure two circles are congruent if they have the same diameter
45/100 x z=72
9/20z=72
z=72/ 9/20
z=160
Hello! To find this answer, we have to do change/original. 9.73 - 9.60= 0.13. 0.13/9.60 = 0.01354 and other numbers behind it or 1.4% when rounded to the nearest tenth. You have to multiply the decimal by 100 in order to to get the percent form. It rounds up to 1.4 instead of back down to 1.3, because the 5 is in the hundredths place, and when anything 5 or more appears behind the digit you are rounding to, you go up. The percent increase is about 1.4%.
