45 minutes is 3/4 of an hour, so find 3/4 of 12.
Divide 12 by 4 to get 1/4 of 12. That is 3.

All 3 sides are equal in an equilateral triangle...
2x - 5 = 3x - 22
-5 + 22 = 3x - 2x
17 = x
2x - 5 = 2(17) - 5 = 34 - 5 = 29
3x - 22 = 3(17) - 22 = 51 - 22 = 29
x + 12 = 17 + 12 = 29
as u can see, all sides measure 29 inches
