45 of them because 45 times 20 = 900
It takes four times because 45+45=90+45=135+45=180. So all of those angles can make a straight line.
6 goes into 45 7.5 times, as there are 7 and a half values of 6 to make 45.
Square root of 45 times square root of 45 = 45
45 x 45 = 2025

(15,3)(9,5)
6 goes into 45 7.5 times, as there are 7 and a half values of 6 to make 45.
They are: 3 times 15 = 45, 9 times 5 = 45 and 1 times 45 = 45

Square root of 45 times square root of 45 = 45
1290
45 x 45 = 2025
44 times 45=1,980
9 times 5 = 45
How about 9 times 5 = 45
