That it equals2.449 i did the math and that is what i got
Yes similar polygons are are two polygons with the same shape but not the same size
Let the angle be x and it's complement be c.
Then, x = c + 88 and x + c = 90
Substitute the first equation in the second.
(c+88) + c = 90
2c+88 = 90
2c = 2
c =1
Compliment = 1
Angle = 89
