The exterior angle is supplementary to the adjacent angle (they form a linear pair) and is the sum of the two angles in the triangle that are not adjacent to it. For example, in number 2, the exterior angle is 28+40=68 degrees. You can use the other method to check. 68 degrees is supposed to be in a linear pair with 112 degrees, which it is. So the answer to number 2 would be 68 degrees.
Try doing this for the rest of them
1 foot = 12 inches
Therefore:
2 feet = 24 inches
------------------
2 feet x 725 = 1450 feet

The real tower is 725 times taller than the actual model.
Ratio:
725 : 1
1) 4
2) 16
3) 16
4) 6
5)12
6) 4
