How many different rectangular arrays can pablo make with all 36 tiles, so none of the arrays show the same factors?

4 and 9 could be 1 array. 2 and 18 can be another array. 3 and 12 could be another one. 6 and 6 could be another array. Lastly, 1 and 36 could be an array. There should be a total of 5 arrays. If you include the 1 and 36 array, then it's 5, I'd you don't include it, then it's 4 arrays.

This polygon has 4 sides
180(4-2) = 180(2) = 360 degree
80+90+2x + 3x = 360
170+5x = 360
5x = 190
x= 38
measure of angle t is 2(38)= 76
the answer is c. trust me
hope this !
