Assuming that means 1.10^t:
0.10 is for years. To get months divide by 12.
0.10/12 = 0.0083333...
And (1+0.083333...) = 1.0833333. (You will have to multiply t by 12 also to get it in terms of months)
(1.0833333)^12t
The biggest side should be the hypotenuse in a right triangle.
In the Pythagorean theorem, side^2 + side^2 = hypotenuse^2
28^2 + 45^2 = 53^2 if these lengths create a right triangle.
Since 28^2 + 45^2 = 2809 and 53^2 = 2809, these sides do in fact form a right triangle.
Can you tell which is the length, width and height?
